You can't have .78 of an atom - atoms are indivisible.
Carbon atoms have 6 electrons, when non-ionized
each of atoms have electrons that equql to atomic number of that of atoms
there are 5 electrons in boron atoms.
two electrons
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
Only two electrons.
Only two electrons.
3 atoms I think.
Nitrogen atoms have two core electrons.
a carbon atom can share electrons with up to four other atoms.
covalent bond (There is also metallic bonding, which is many, many atoms sharing an electron, not just neighboring electrons.)
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
