The answer to your question is Antimony chloride or Antimony trichloride

Formula SbCl₃

Explanation:

Data

Cation Anion

51 protons 1/3 of the protons of the cation

48 electrons electrons = protons + 1

Process

1. - Look for the element that has an atomic number of 51

Antimony = Sb

- It has 48 electrons, that means its charge is

51 - 48 = 3

-Then, the formula of Antimony is

Sb⁺³

2. - Divide 51 by 3

51/3 = 17

-Look for the element with an atomic number of 17

-This element is Chlorine

Cl

-Calculate the charge of Chlorine

17 - 18 (17 + 1) = - 1

-Then, the formula of chlorine is

Cl⁻¹

3. - Write the formula of the compound

Sb⁺³ + Cl⁻¹ = SbCl₃

4. - Write the name of the compound.

This compound is a binary salt, so, it is called

Antimony chloride or Antimony trichloride
