How many protons does patassium have?

Answer 1

A potassium atom has 19 protons.

An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.

Answer 2

The number of protons that an element has is equal to its atomic number. To find potassium's atomic number, one just needs to look at a Periodic Table. We see from there that potassium's atomic number is 19, thus it has 19 protons.

Answer 3

There are 19 protons in the potassium atom.

Answer 4

One atom of potassium contains 19 protons. This is the same as its atomic number, 19.

Answer 5

Any ion of potassium has 19 protons

Answer 6

An atom of potassium has 19 protons.

Answer 7

19

Answer 8

19 protons.
