Metals Nonmetals and Metalloids

  1. 1. 1. Elements in the same row belong to the same . period 2. Elements in the same column are group members of the same . 3. Elements that have many similar group . properties belong to the same 4. Generally, the atomic mass of elements as increases you move from left to right and from top to bottom on the Periodic Table.
  2. 2. Soft Silvery solid metalloid 72 Reacts very slowly with oxygen
