Hydrogen
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
all atoms have different numbers of electrons hydrogen=1 Ununoctium=118
If the atomic number is 118, the number of protons is 118. Atomic number is the number of protons in the nucleus of an atom. The elements are arranged in increasing order of atomic number. All of the atoms of an individual element have the same atomic number. Atomic number identifies an element.
Any neutral atoms has the same number of electrons as protons, and any atom has a number of protons equal to the difference between its mass number and neutron number. Therefore, this atom has 197 - 118 = 79 electrons.

Ununoctium has an atomic number of 118, in the neutral atom it will therefore have 118 electrons.
An isotope is where an atom has a different number of neutrons than what it should be.e.g.Gold has 79 protons and 118 neutrons = 197 nucleons.But some gold atoms are strange they only have 117 neutrons.They are isotopes.
