- Medical terms are made up of elements including roots, suffixes, prefixes, and combining vowels. Understanding these elements is important for analyzing terms.
- Common prefixes include hypo-, epi-, and cis-. Common suffixes include -itis, -algia, and -ectomy.
- Dozens of combining forms are provided, such as gastro- meaning stomach, cardi- meaning heart, and aden- meaning gland.
- Rules are provided for analyzing terms, such as reading from the suffix backward and dropping combining vowels before suffixes starting with vowels

Nerve cells, also known as neurons, are highly specialized cells that process and transmit information through electrical and chemical signals. This chapter discusses the structure and function of neurons, how they communicate with each other via synapses, and how signals are propagated along neurons through changes in their membrane potentials. Neurons play a vital role in the nervous system by allowing organisms to process information and coordinate their responses.

This chapter discusses microfilaments, which are one of the three main types of cytoskeletal filaments found in eukaryotic cells. Microfilaments are composed of actin filaments and play important roles in cell motility, structure, and intracellular transport.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

neutral formula.
PROBLEM: Give the systematic name for each formula or the
formula for each name for the following compounds:
(a) tin(II) fluoride (b) CrI3 (c) ferric oxide (d) CoS
(a) Tin(II) is Sn2+; fluoride is F-; so the formula is SnF2.
(b) The anion I- is iodide; 3I- means that Cr (chromium) is +3. CrI3 is
chromium(III) iodide.
(c) Ferric is a common name for Fe3+; oxide is O2-; therefore the formula
is Fe2O3.
(d) Co is cobalt; the anion S2- is sulfide; the compound is cobalt(II)
sulfide.

Sample Problem 2.10 Determining Names and Formulas of Ionic
Compounds Containing Polyatomic Ions
SOLUTION:
PLAN: Remember to use parentheses when more than one unit
of a particular polyatomic ion is present in the compound.
(a) ClO4
- is perchlorate; Fe must have a 2+ charge since
there are 2 ClO4
- ions. This is iron(II) perchlorate.
(b) The anion sulfite is SO3
2-; therefore you need 2 Na+ for
each sulfite. The formula is Na2SO3.
(c) The ionic compound is barium hydroxide. When water
is included in the formula, we use the term “hydrate” and a
prefix that indicates the number of molecules of H2O. This
compound is barium hydroxide octahydrate.
PROBLEM: Give the systematic name for each formula or the formula
for each name for the following compounds:
(a) Fe(ClO4)2 (b) sodium sulfite (c) Ba(OH)2·8H2O
33. 2-33
Sample Problem 2.11 Recognizing Incorrect Names and
Formulas of Ionic Compounds
SOLUTION:
(a) The charge of Ba2+ must be balanced by two C2H3O2
- ions. The
prefix “di” is not required and is not used in this way when naming
ionic compounds. The correct name is simply barium acetate.
(b) An ion of a single element does not need parentheses, and sulfide
is S2-, not SO3
2-. The correct formula is Na2S.
PROBLEM: There is an error in the second part of each statement.
Provide the correct name or formula in each case.
(a) Ba(C2H3O2)2 is called barium diacetate.
(b) Sodium sulfide has the formula (Na)2SO3.
(c) Iron(II) sulfate has the formula Fe2(SO4)3.
(d) Cesium carbonate has the formula Cs2(CO3).
34. 2-34
(c) Sulfate or SO4
2- has a 2- charge, and only one Fe2+ is needed to
form a neutral compound. The formula should be FeSO4.
(d) The parentheses are unnecessary, since only one CO3
2- ion is
present. The correct formula is Cs2CO3.
Sample Problem 2.11
35. 2-35
Naming Acids
1) Binary acid solutions form when certain gaseous
compounds dissolve in water.
For example, when gaseous hydrogen chloride (HCl) dissolves in
water, it forms a solution called hydrochloric acid.
Prefix hydro- + anion nonmetal root + suffix -ic + the word acid -
hydro + chlor + ic + acid
hydrochloric acid
2) Oxoacid names are similar to those of the oxoanions,
except for two suffix changes:
-ate in the anion becomes –ic in the acid
-ite in the anion becomes –ous in the acid
The oxoanion prefixes hypo- and per- are retained. Thus,
BrO4
- is perbromate, and HBrO4 is perbromic acid;
IO2
- is iodite, and HIO2 is iodous acid.
36. 2-36
Binary Compounds
• D. Acids: Hydrogen plus nonmetal
– Gas: hydrogen (stem)ide
– Aqueous solution: hydro(stem)ic acid
• HCl, HCl(g) hydrogen chloride
• HCl(aq) hydrochloric acid
• See also pages 64-65 for acid
nomenclature.
38. 2-38
Sample Problem 2.12 Determining Names and Formulas of
Anions and Acids
SOLUTION:
PROBLEM: Name the following anions and give the name and
formula of the acid derived from each:
(a) Br - (b) IO3
- (c) CN - (d) SO4
2- (e) NO2
-
(a) The anion is bromide; the acid is hydrobromic acid, HBr.
(b) The anion is iodate; the acid is iodic acid, HIO3.
(c) The anion is cyanide; the acid is hydrocyanic acid, HCN.
(d) The anion is sulfate; the acid is sulfuric acid, H2SO4.
(e) The anion is nitrite; the acid is nitrous acid, HNO2.
39. 2-39
Naming Binary Covalent Compounds
A binary covalent compound is typically formed by the
combination of two non-metals.
Some of these compounds are very common and have trivial
names, eg., H2O is water.
For a binary covalent compound, the element with the
lower group number in the periodic table is first in the
name and formula. Its name remains unchanged.
The element that is second is named using the root with
the suffix –ide. Numerical prefixes indicate the number of
atoms of each element present.
40. 2-40
Binary Compounds
• C. Molecular compounds; two nonmetals
– Less electronegative + stem of the more electronegative + ide
– Use numerical prefixes (Greek)
1 mono- 5 penta- 9 nona-
2 di- 6 hexa- 10 deca-
3 tri- 7 hepta-

Elements classified as metalloids are also named as nonmetal –

Sample Problem 2.13 Determining Names and Formulas of
Binary Covalent Compounds
SOLUTION:
PROBLEM: (a) What is the formula of carbon disulfide?
(c) Give the name and formula of the compound whose
molecules each consist of two N atoms and four O atoms.
(b) What is the name of PCl5?
(a) Carbon is C, sulfide is sulfur S and di-means two; the formula is CS2.
(b) P is phosphorous, Cl is chloride, the prefix for 5 is penta-.
This is phosphorous pentachloride.
(c) N is nitrogen and is in a lower group number than O (oxygen).
The compound formula is N2O4 and the name is dinitrogen
tetraoxide.
43. 2-43
Sample Problem 2.14 Recognizing Incorrect Names and
Formulas of Binary Covalent Compounds
SOLUTION:
(a) The prefix mono- is not needed if there is only one atom of the
first element, and the prefix for four is tetra-. So the name is
sulfur tetrafluoride.
(b) Hepta- means 7; the formula should be Cl2O7.
(c) The first element is given its elemental name so this is
dinitrogen trioxide.
(a) SF4 is monosulfur pentafluoride.
(c) N2O3 is dinitrotrioxide.
(b) Dichlorine heptaoxide is Cl2O6.
PROBLEM: Explain what is wrong with the name of formula in the
second part of each statement and correct it:
