Knowing which element it is and its formal charge, subtract the charge from its atomic number.
A neutral atom with 49 protons has 49 electrons.
Helium atom has 2 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Sodium has 11 electrons.
It depends on the atom you are reffering to, but to find the electrons take away the number of protons from the mass number of the atom.
A neutral atom with 49 protons has 49 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
there are 12 electrons in carbon. you can find this out by looking at the "ATOMIC NUMBER"
Aluminium is a metal element. There are 13 electrons in a single atom.
Carbon has for valence electrons for forming covalent bonds.
A nitrogen atom has seven electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
To find the valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
