Question

fill in the name and empirical formula of each ionic compound that could be formed from the ions in this table
some ionic compounds
cation anion empirical formula name of compound
$sr^{2 + }$ $s^{2 - }$
$sr^{2 + }$ $n^{3 - }$
$sr^{2 + }$ $p^{3 - }$
$sr^{2 + }$ $o^{2 - }$

Explanation:

Step1: Determine formula for Sr²⁺ and S²⁻

The charges of Sr²⁺ and S²⁻ are equal in magnitude. So, the empirical formula is SrS. The name is strontium sulfide.

Step2: Determine formula for Sr²⁺ and N³⁻

To balance the charges, we need 3 Sr²⁺ (total charge +6) and 2 N³⁻ (total charge - 6). The empirical formula is Sr₃N₂. The name is strontium nitride.

Step3: Determine formula for Sr²⁺ and P³⁻

To balance the charges, we need 3 Sr²⁺ (total charge +6) and 2 P³⁻ (total charge - 6). The empirical formula is Sr₃P₂. The name is strontium phosphide.

Step4: Determine formula for Sr²⁺ and O²⁻

The charges of Sr²⁺ and O²⁻ are equal in magnitude. So, the empirical formula is SrO. The name is strontium oxide.

Answer:

cation	anion	empirical formula	name of compound
Sr²⁺	N³⁻	Sr₃N₂	strontium nitride
Sr²⁺	P³⁻	Sr₃P₂	strontium phosphide
Sr²⁺	O²⁻	SrO	strontium oxide
