How many electrons,protons and neutrons are present in one molecule of glucose?

A glucose molecule has 96 protons, 84 neutrons and 96 electrons.

A glucose molecule's chemical formula is: $C_6{H}_{12}{O}_6$.

This is made up of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.

For each $C$ there are - 6 protons, 6 electrons and 6 neutrons

For each $H$ there is - 1 proton, electron and no neutrons

For each $O$ there are - 8 protons, 8 electrons and 8 neutrons

So in $C_6{H}_{12}{O}_6$ there are:

$C:6\times 6=$ 36 protons, 36 electrons and 36 neutrons

$H:1\times 12=$ 12 protons, 0 electrons and no neutrons

$O:8\times 6=$ 48 protons, 48 electrons and 48 neutrons
