An oxygen atom has always 8 electrons (unless it's an ion where it has picked up 2 electrons and carries a -2 charge).
In an O2 molecule there are 2*8 = 16 electrons and in an O3 molecule there are 3*8 = 24 electrons.
An atom of an element contains 66 electrons. What element is it?
8
eight
How many litres of oxygen is 28 % using a face mask?
Oxygen does not have corners.
Four oxygen atoms.
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
2 nitrogen and 4 oxygen ,,,,,,NO Problem
845
electrons are shared in two shells, 2 in the first and 6 in the second
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
eletrons
count the number of protons which will be equal to number of electron.
Oxidising is losing eletrons
OH3+ contains 1 oxygen with 8 protons and three H each with one proton, making 11 in all. As it has a single positive charge the number of electrons is 10.
Electrons have a negative charge (-1).
eletrons
no they are found around the nucleus
Aluminium lends it's eletrons, it does not borrow it.
When an atom forms an ion.When gaining or giving eletrons.
