Answer

Explanation:

Step1: Answer question 1

On the periodic - table, metals are on the left - hand side and non - metals are on the right - hand side. One would label the left - hand area as metals and shade in the right - hand elements as non - metals.

Step2: Answer question 2

Compounds made from a metal and non - metal are called ionic compounds.

Step3: Answer question 3

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Step4: Answer question 4

In $CaBr_{2}$, the number of $Ca^{2 + }$ ions is 1 and the number of $Br^{-}$ ions is 2.

Step5: Answer question 5

In $Sr_{3}(PO_{4}){2}$, the number of $Sr^{2+}$ ions is 3 and the number of $PO{4}^{3 - }$ ions is 2.

Step6: Answer question 6

Compounds made from 2 non - metals are called molecular compounds.

Step7: Answer question 7

In $P_{4}O_{10}$, the number of P atoms is 4 and the number of O atoms is 10.

Step8: Answer question 8

The name of each molecular compound ends in - ide.

Answer:

  1. Label left - hand area as metals and shade right - hand elements as non - metals on periodic table.
  2. Ionic
  3. An atom or molecule with a net electrical charge due to electron loss or gain.
  4. $Ca^{2+}$: 1, $Br^{-}$: 2
  5. $Sr^{2+}$: 3, $PO_{4}^{3 - }$: 2
  6. Molecular
  7. P: 4, O: 10
