How many neutrons does k have?

Answer 1

That is potassium which occurs naturally in three isotopes, 39K, 40K and 41K. The numbers of neutrons in the nuclei of atoms of these isotopes are 20, 21 and 22 respectively. Please see the link.

Answer 2

As you might already know, an atom consists of three different elements: electrons, protons and neutrons. The electrons are negatively charged, the protons positively charged, and the neutrons are neutrally charged.

To make it simple, the neutrons' "job" is to kind of keep the negative and the positive charges away from each other. Imagine two gangs fighting each other, and the neutrons are police forces trying to keep the situation under control.

The reason why K (Potassium) contains more neutrons than protons is simply because more neutrons are required for this job. If you look at the even heavier atoms, like for instance Uranium, they contain many more neutrons than protons.

As a side note, this is one of the essential steps of making an atomic bomb. By manually removing some neutrons, the negative and positive charges collide and create a massive explosion.

Answer 3

K (potassium) itself is an element, not an isotope. There are 3 potassium isotopes, with 20, 21, and 22 neutrons.

Answer 4

There are 20.1 neutrons in potassium (39.1-19).

Answer 5

The element potassium (K) usually has 20 neutrons. However, the number of neutrons can vary in isotopes of potassium.

Answer 6

It has 20 neutrons.
