Question

Write an equation that shows the formation of a potassium ion from a neutral potassium atom

Answer 1

The formation of a potassium ion from a neutral potassium atom is represented by the equation K → K+ + e−, where the potassium atom loses one electron to become a potassium ion with a 1+ charge.

Step-by-step explanation:

To represent the formation of a potassium ion from a neutral potassium atom, you can write the following chemical equation: K → K+ + e−

This equation shows that a potassium atom (K) loses one electron (e−) to become a potassium ion (K+). The potassium ion has a charge of 1+, indicating it has one fewer electron than protons, giving it a net positive charge.

Answer 2

Metals usually donates electrons. The concept behind this phenomenon is stability. The elements with the most stable electronic configuration are the noble gases in Group 5A. As a result, the other elements donate or accept electrons so that they would be like the noble gases. Since metals are past their nearest noble gas element, they have to shed their electrons. When they do, they become cations which are positively charged ions.

K → K⁺ + e⁻
where e is an electron donated
