Question

Write the formula of compound formed in the reaction between lithium and bromine?

Answer 1

The compound formed between lithium and bromine is lithium bromide, with the chemical formula LiBr.

Step-by-step explanation:

The formula of the compound formed in the reaction between lithium (Li) and bromine (Br2) is lithium bromide (LiBr). In this ionic compound, lithium, which is in Group 1 of the periodic table, has a +1 charge (Li+), and bromine, present in Group 17, has a -1 charge (Br-). When they react, they form an ionic bond, and one lithium ion balances one bromine ion, resulting in a formula of LiBr for lithium bromide.

Answer 2

The formula for the compound formed between lithium and bromine is LiBr, which is an ionic compound consisting of one lithium ion and one bromine ion.

Step-by-step explanation:

The formula of the compound formed in the reaction between lithium and bromine is LiBr. Lithium (Li) has a charge of +1 and bromine (Br) has a charge of -1. When these two elements react, they form an ionic compound because lithium donates its single valence electron to bromine, resulting in a stable octet for bromine.

In forming the compound, each lithium ion (Li+) pairs with a bromine ion (Br−) to produce lithium bromide (LiBr), which is the neutral compound formed. The charges of the ions are understood to balance out, as there is one of each ion, so the overall charge of the compound is zero.
