Periodic table by Cassidy Estabrooke
The periodic table was developed in 1869 by Dmitri Mendeleev, who organized the elements into a table based on increasing atomic number and recurring chemical and physical properties. The table is organized into periods from left to right and groups, with elements grouped according to their position on the table sharing similar properties. Elements can also be grouped as metals and non-metals. The location of an element on the periodic table relates to its atomic mass and allows elements to be grouped based on similar properties.
Conly's periodic table pres
Dimitri Mendeleev created the first periodic table of chemical elements in 1869 while working as a chemistry professor in Russia. He arranged the 63 known elements according to their atomic masses, placing similar elements in columns. This organization revealed patterns in elements' chemical and physical properties. The periodic table has since been expanded and refined as new elements have been discovered, but Mendeleev's original layout established the foundation for understanding the relationships between elements.

Review for quiz
Dmitri Mendeleyev created the periodic table by organizing the elements on cards based on their properties, arranging them in rows and columns. This allowed for the prediction of yet-to-be discovered elements, leaving gaps. Gases are composed of particles that are not connected and are in constant motion, taking up space between one another through compression and expansion based on kinetic energy levels that control particle speed and distance.

Periodic table
The document discusses the periodic table. It defines the periodic table as the tabular arrangement of chemical elements based on their atomic numbers, with vertical columns called groups and horizontal rows called periods. Properties of elements are periodic functions of their atomic numbers. The modern periodic table is based on the periodic law proposed by Henry Moseley. While scientists proposed various early forms, Dmitri Mendeleev developed the renowned 1869 periodic table that was systematically devised with empty cells for missing elements. The modern periodic table contains 118 total elements, with 94 naturally occurring on Earth and the rest synthetic.
The Periodic Table
Dmitri Mendeleev created the Periodic Table of Elements by noticing that elements with similar properties seemed to repeat in a predictable pattern. The Periodic Table arranges elements in rows and columns, with the rows called periods increasing in atomic number from left to right and the columns called groups having similar properties. Elements closer together on the table, whether in the same period or group, are more chemically similar. Hydrogen, helium, and lithium are the first three elements, with their atomic numbers, masses, and common uses described.

Development of the periodic table
The document summarizes the development of the periodic table over time by various scientists from the 17th century to today. Dmitri Mendeleev produced one of the first recognizable periodic tables in 1869, arranging elements based on atomic weight and leaving gaps for undiscovered elements.

The periodic table is now a fundamental tool that organizes all the known elements according to their atomic structure.
Development of the Periodic Table
Chemists have always looked for ways of arranging the elements to reflect the similarities between their properties. The modern periodic table lists the elements in order of increasing atomic number (the number of protons in the nucleus of an atom). Historically, however, relative atomic masses were used by scientists trying to organise the elements. This was mainly because the idea of atoms being made up of smaller sub-atomic particles (protons, neutrons and electrons) had not been developed. Nevertheless, the basis of the modern periodic table was well established and even used to predict the
The periodic table
The periodic table arranges the chemical elements in order of atomic number so that elements with similar properties fall into columns known as groups. The standard periodic table includes periods (horizontal rows) and groups (vertical columns), with elements in the same group having similar properties. Dmitri Mendeleev is credited with developing the first recognizable periodic table in 1869, arranging the known elements based on their atomic masses and properties. While earlier scientists like Lavoisier and Döbereiner identified patterns among elements, Mendeleev's periodic table was the first to systematically organize all known elements and also predict properties of undiscovered elements.

Periodic table
Dmitri Mendeleev created the periodic table in 1869 by arranging known elements in order of atomic weight and grouping them into columns and rows based on their chemical and physical properties. Elements are arranged with metals on the left, non-metals on the right, and metalloids in between. Elements in the same vertical group have similar properties due to their shared number of valence electrons. Elements are also arranged horizontally in periods based on the number of electron shells in their atoms. The periodic table organizes elements based on atomic structure and recurring trends in physical and chemical properties.
5.6 History of the Periodic Table
Mendeleev organized the periodic table by arranging elements in order of increasing atomic mass, which allowed elements with similar properties to line up in regular intervals. Some inconsistencies remained unresolved until Moseley discovered that arranging elements by atomic number eliminated all inconsistencies. The periodic table continues to be refined, with the addition of noble gases in the 1800s and recognition of lanthanide and actinide series in the 1900s. The periodic law states that when elements are arranged by atomic number, their chemical and physical properties repeat periodically.

Here is a sample dance teaching plan for a Year 3-4 class on the topic of "Animals":
WARM UP (5 mins)
- Animal walks around the space: walk like different animals such as elephant, monkey, snake etc.
- Stretching: arm stretches, leg stretches, torso twists to warm up the body.
EXPLORATION (10 mins)
- Teacher introduces the idea that we can tell stories through dance by showing movements.
- In pairs, students choose an animal and explore movements, gestures and facial expressions to portray their animal. They take turns to show their animal to their partner and guess what it is.
DEVELOPMENT (10 mins)

Periodic table keynote
- 1. The Periodic Table By: Katie Wentz
- 2. Who/When/Why Dmitri Mendeleev came up with the idea In 1869 He came up with it to organize elements and provide physical and chemical properties
- 3. How is the table organized? It is organized by the increasing of atomic number They are also grouped together based on their chemical and physical properties.
- 4. Rows of Elements We call the horizontal rows of elements periods. And the vertical rows groups.
- 5. Oxygen Atomic Number: 8 Element Symbol: O Atomic Mass: 15.9994 Examples: Air Additional Info: We wouldn't be able to live without i
- 6. Gold Atomic Number:79 Element Symbol:Au Atomic Mass: 196.96655 Examples: Jewelry Additional Info: Obtained From: crust of the earth
- 7. Sodium Atomic Number: 11 Element Symbol: Na Atomic Mass: 22.98977 Examples: Medicine Additional Info: Came from table salts
