How many protons, neutrons, and electrons does potassium's neutral atom have?

Answer 1

Number of Protons 19

Step-by-step explanation:

Number of Neutrons 20

Number of Electrons 19

Melting Point 63.65° C

Answer 2

The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.

Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
