Which element has the lowest number of electrons?
Hydrogen , with ONE electron. Hydrogen exists as three isotopes. Here are the atomic arrangements for these isotopes. protium ; 1 proton , 0 neutrons , 1 electron ( commonest form of hydrogen) deuterium ; 1 proton , 1 neutron , 1 electron ( known as heavy hydrogen/water) Tritium ; 1 proton , 2 neutrons , 1 electron ( radio-active and known as 'super heavy hydrogen). Note , in all cases there is only ONE proton/electron. However, the number of neutrons varies. protium (hydrogen) symbol H . Atomic Mass '1'. deuterium symbol D ; Atomic mass '2'. Tritium symbol T ; atomic mass '3'. NB THe next element in the Periodic Table is Helium(He) Atomic No. 2. Atomic Mass '4. Made up aS;- 2 PROTONS, 2 NEUTRONS AND 2 ELECTRONS. ET SEQ.,

atomic number
Why is hydrogen given the number one?
Hydrogen is given the number one in the periodic table because it has one proton in its nucleus. The atomic number of an element corresponds to the number of protons in its nucleus, which helps to distinguish one element from another.
