Answer:

The answer is 1722 e⁻

Explanation:

Let's make a rule of three:

9.708×10⁻³¹ kg is the mass of 1 e⁻

1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?

1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg

The answer is 1722 e⁻

Write an equation that shows the formation of a barium ion from a neutral barium atom.
Colt1911 [192]

Answer:

Ba -> Ba2+ + 2e-

Explanation:

A neutral atom becomes an iron when that atom loses electrons. The number of electroms lost by that atom determines the ionic charge or charge of it's ion. In this case, a neutral Barium atom (Ba) will become a barium ion, which has a charge of +2, when it loses 2 electrons to a more electronegative atom in a reaction.

The equation is:

Ba -> Ba2+ + 2e-

2e- is the two electrons lost
