What is the total number of electrons in a water molecule?

Answer 1

Water molecules are composed of two atoms of hydrogen and one atom of oxygen. The hydrogen atoms each bring an electron to the reaction, and the oxygen atom brings eight. The resulting molecule has two plus eight electrons, or ten electrons in it.

Answer 2

In a water molecule (not an ion - just the molecule) the protons and electrons are matched in number. The hydrogen has 1 proton each. Oxygen has 8 protons. Since water is H2O, you have 2x1 + 8 = 10 protons - and consequently 10 electrons.

Water can form ions which have more or less electrons but the non-ionic molecule will always have exactly 10.

Answer 3

There are 10 electrons in a molecule of water. This is because the chemical formula of a water molecule is H2O, denoting a bonding of two hydrogen atoms to an oxygen atom. To find out how many electrons exist in a molecule of water, one can simply sum the electrons from its components. Since the number of electrons in a neutral atom is equal to its atomic number, referencing a periodic table would give the following information:

Hydrogen has one electron

Oxygen has eight electrons

Since there are two hydrogen atoms present, its number of electrons must be multiplied by two. The following equation represents the number of electrons in a water molecule:

# of electrons=(2x1)+(1x8)

# of electrons=10

Answer 4

2 x 1 for the two Hydrogen atoms + 1 x 8 for the only oxygen in H2O: together 12 electrons in a water molecule.

Answer 5

One with each hydrogen and six with the oxygen. There are 8 electrons in each H2O molecule.

Answer 6

10
