Every atom has electrons equal to the no. of its atomic no.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
No, an electron is a subatomic particle that is not composed of atoms. It is one of the fundamental particles that make up an atom, along with protons and neutrons. Electrons are negatively charged and orbit the nucleus of an atom.
the quantum number n determines the energy of an electron in a hyrdogen atom.
Only two electron shells.
Magnesium has 3 electron shells.
The chemical formula is NH31+ so there are 3 hydrogen atoms but one of the hydrogen atoms is missing its electron.
The uranium atom has seven electron shells.
Aluminum has 3 valence electrons.
8 valence electrons
Hydrogen atoms have one valence electron which is also the only electron they have.
covalent bond (There is also metallic bonding, which is many, many atoms sharing an electron, not just neighboring electrons.)
There is one electron in sodium's valance shell.
