Potassium/Atomic number

What is the total number of neutrons in the nucleus of a neutral atom that has 19?

20 neutrons
19 protons, 20 neutrons and 18 electrons.

### How many protons neutrons and electrons are in potassium K )?

This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons. To find out the number of neutrons you have to look at the atomic mass or weight of the element. This can also be found in the periodic table.

## How many protons and electrons are there in potassium?

So in the case of potassium, there are 19 protons as well as 19 electrons. The number of neutrons contained in potassium is a little more complicated. This is not summarily listed on the Periodic Table but can be easily derived by looking at the other number on the chart, an element’s atomic weight.

## What is the total number of protons in Silicon?

Atomic Number – Protons, Electrons and Neutrons in Silicon Silicon is a chemical element with atomic number 14 which means there are 14 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.

How many neutrons and electrons are in Silicon 29Si?

Out of these, only 29Si is of use in NMR and EPR spectroscopy, as it is the only one with a nuclear spin (I = 1/2). Silicon-28 is composed of 14 protons, 14 neutrons, and 14 electrons. Silicon-29 is composed of 14 protons, 15 neutrons, and 14 electrons.
