Number Of Electrons Of Oxygen

Chalkboard with description of periodic table notation for oxygen. There is a square with three values in it. Top has atomic number, center has element symbol, and bottom has atomic mass value. The atomic number equals number of protons and also the number of electrons in a neutral atom. Atomic mass equals the mass of the entire atom.

Check out the blackboard. That box on the left has all of the information you demand to know about one chemical element. Information technology tells y'all the mass of one atom, how many pieces are inside, and where information technology should be placed on the periodic table.

In the next section we're going to cover electron orbitals or electron shells. This may be a new topic to some of you lot.

Electrons In The Shells

Have a look at the picture below. Each of those colored balls is an electron. In an atom, the electrons spin around the centre, also chosen the nucleus. The electrons similar to exist in separate shells/orbitals. Vanquish number one can only concord 2 electrons, beat out two tin concord 8, and for the showtime xviii elements shell three can hold a maximum of viii electrons. As you learn about elements with more than than xviii electrons you lot volition observe that shell iii tin hold more than than 8. Once one vanquish is full, the side by side electron that is added has to move to the next vanquish.

Then... for the element of OXYGEN, you already know that the atomic number tells yous the number of electrons. That ways there are 8 electrons in an oxygen atom. Looking at the picture, yous can encounter there are ii electrons in shell one and 6 in trounce 2.
