(opposite spins). Electron shell #1 has the lowest energy and its s-orbital is the first to be filled. Shell #2 has four higher energy orbitals‚ the 2s-orbital being lower in energy than the three 2p-orbitals. (x‚ y & z). As we progress from lithium (atomic number=3) to neon (atomic number=10) across the second row or period of the table‚ all these atoms start with a filled 1s-orbital‚ and the 2s-orbital is occupied with an electron pair before the 2p-orbitals are filled. In the third period

energy is the measure of energy needed to remove a mole of electrons from a mole of gaseous atoms to form a mole of positively charged gaseous ions‚ also known as a cation. The general trend is that as the atomic number increases between elements Lithium to Neon the level of the first ionisation energy increases‚ as there is a stronger nuclear attraction. [Braid‚ K. et al. (2015)]. The stronger nuclear attraction along the period is caused by the number of protons increasing. When the nucleus has
