The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8.
For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
The Element Neon has 10 protons and 10 electrons.
43 electrons :)
4 electrons, 2 valence electrons
Argon has 18 electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Oxygen is a non metal element. There are 16 electrons in a single atom.

Thorium has 90 electrons.
4 electrons, 2 valence electrons
Gold is a metal element. There are 79 electrons in a single atom.
No neutral element has these characteristics. However, the oxide ion, O-2, does have them.
In cesium, there are 54 core electrons. This is calculated by subtracting the number of valence electrons (1) from the total number of electrons in cesium, which is 55. Core electrons are the inner electrons that are not involved in chemical bonding.
Thorium has 90 electrons.
