Bromine has the atomic number 35. Bromine atoms often have 36 electrons, making them have this overall charge:

A. -1

B. +1

C. -2

D. +2

Respuesta :

Answer: A) -1

Explanation:

Answer: The correct answer is Option A.

Explanation:

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.
  • When an atom gains electrons, it results in the formation of negative ion known as anion.

We are given:

Atomic number of bromine = Number of protons in bromine atom = 35

Number of electrons = 36

Number of electrons = Number of protons - charge

Charge = 35 - 36 = -1

Bromine atom is forming an anion having -1 charge

Hence, the correct answer is Option A.
