How many protons and electrons does K have?

Answer 1

19 electrons, 19 protons and 20 neutrons

Answer 2

In a neutral atom, potassium will have the same number of electrons as protons, which is the same as the atomic number, 19. However, a potassium ion will lose just one electron.

See related question below.

Answer 3

The number of protons is always the atomic number -- 19

The number of electrons is the number of protons minus the charge -- 19-1=18

Note: If it was an F minus ion (or something similar), then you would do 9-(-1), which is 9+1=10;

Answer 4

An electric-neutral K atom has 19 protons and 19 electrons.

Answer 5

Potassium (K) has 19 electrons in its neutral atom.

Answer 6

If by "k" you mean the element number "k", then it will have "k" protons, "k" electrons if it is neutral, and a variable number of neutrons.

Answer 7

Potassium contains 20 protons. it contains 20 electrons.

Answer 8

There are 19 protons in the ion. but there are only 18 electrons.

Answer 9

It has 19 electrons and protons.
