A binary ionic compound is known to contain a cation with 51 protons and 48 electrons. The anion contains one-third the number of protons as the cation. The num - ber of electrons in the anion is equal to the number of protons plus 1. What is the formula of this compound? What is the name of this compound?

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
