Question

metal nonmetal formula bonding diagram

1. lithium bromine libr
2. magnesium chlorine mgcl₂
3. sodium oxygen na₂o
4. beryllium sulfur bes
5. aluminum iodine ali₃

Explanation:

Step1: Lithium (Li⁺) and bromine (Br⁻)

Li⁺ (+1) and Br⁻ (-1) balance; formula LiBr.

Step2: Magnesium (Mg²⁺) and chlorine (Cl⁻)

Mg²⁺ (+2) needs 2 Cl⁻ (-1 each); formula MgCl₂.

Step3: Sodium (Na⁺) and oxygen (O²⁻)

2 Na⁺ (+1 each) balance O²⁻ (-2); formula Na₂O.

Step4: Beryllium (Be²⁺) and sulfur (S²⁻)

Be²⁺ (+2) and S²⁻ (-2) balance; formula BeS.

Step5: Aluminum (Al³⁺) and iodine (I⁻)

Al³⁺ (+3) needs 3 I⁻ (-1 each); formula AlI₃.

Answer:

1. LiBr
2. MgCl₂
3. Na₂O
4. BeS
5. AlI₃
