## What is the atomic number of silicon 29?

Element Name Silicon
Element Symbol Si
Atomic Number 14

## What is the atomic mass of Si-29?

The mass and natural abundance of Si-29 are 28.9765 amu and 4.67%, respectively.

## How many protons electrons and neutrons does Si-28 have?

The atomic number is equal to the number of protons in the atom, therefore silicon has 14 protons. In a neutral species, the number of protons equals the number of electrons so silicon also has 14 electrons. The mass number is the number of protons plus neutrons, therefore 28 – 14 protons equal 14 neutrons.

## What is the atomic number of silicon?

Silicon is a chemical element with symbol Si and atomic number 14.

## How many neutrons does silicon 29 have?
