Give the name and formula of each of the binary compounds formed from the following elements. a. Li and N b. Na and Br c. K and S

Short Answer

Expert verified
The binary compounds formed are as follows: a. Lithium Nitride (Li₃N) b. Sodium Bromide (NaBr) c. Potassium Sulfide (K₂S)

Step by step solution

01

a. Li and N Binary Compound Formation

First, we will identify the valency of the elements. - Lithium (Li) is an alkali metal with a valency of +1 (loses 1 electron). - Nitrogen (N) is a non-metal with a valency of -3 (gains 3 electrons). Now, we will use the valencies to make them equal by taking the least common multiple. - Lithium Nitride (Li₃N): \(3 \times (+1)\) for Li to balance \(1 \times (-3)\) for N. So, the formula for the binary compound formed by Li and N is Li₃N, and the compound's name is Lithium Nitride.
02

b. Na and Br Binary Compound Formation

First, we will identify the valency of the elements. - Sodium (Na) is an alkali metal with a valency of +1 (loses 1 electron). - Bromine (Br) is a halogen with a valency of -1 (gains 1 electron). Now, we will use the valencies to make them equal. - Sodium Bromide (NaBr): \(1 \times (+1)\) for Na to balance \(1 \times (-1)\) for Br. So, the formula for the binary compound formed by Na and Br is NaBr, and the compound's name is Sodium Bromide.
03

c. K and S Binary Compound Formation

First, we will identify the valency of the elements. - Potassium (K) is an alkali metal with a valency of +1 (loses 1 electron). - Sulfur (S) is a non-metal with a valency of -2 (gains 2 electrons). Now, we will use the valencies to make them equal by taking the least common multiple. - Potassium Sulfide (K₂S): \(2 \times (+1)\) for K to balance \(1 \times (-2)\) for S. So, the formula for the binary compound formed by K and S is K₂S, and the compound's name is Potassium Sulfide.
