## Why does silicon have 15 neutrons?

Explanation: If it’s 29Si , the superscript refers to the number of massive nuclear particles: 14 protons, obviously (why?), and necessarily 15 neutrons, i.e. isotopic mass = 14+15 , to make up the isotopic mass.

## How many nuclei does silicon have?

The average silicon atom has fourteen protons, fourteen electrons, and most have 14 neutrons. This is a digram of a silicon atom. This shows the 14 protons in the nucleus and where the 14 electrons are located. The four electron, highlighted in green, that are located in the outer ring are the valence electrons.

## Why silicon has no overall charge?

The protons and neutrons, which are approximately equal in size, make up the close-packed central “nucleus” of the atom. Although the atom is built from oppositely charged particles, its overall charge is neutral because it contains an equal number of positive protons and negative electrons.

## How do you calculate isotopic abundance?

As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1. Note that this equation is limited to two isotopes.

## Is Silicon 30 stable?

Silicon-30) is a stable (non-radioactive) isotope of Silicon. It is both naturally occurring and produced by fission.

Si

## What does Silicon 30 contain?

30 neutrons. Silicon-30 is an isotope of Silicon. It has a mass number of 30. The mass number is protons + neutrons.

## Is Silicon an anion?

Silicon is nether a cation nor anion. It is an element. Si. Atom = a monoatomic species which is neutral(No charge on it).
