Test for steroids in sport 2 of 10 First ionisation energy The energy needed to remove one electron from each atom of 1 mole of gaseous atoms to form 1 mole of gaseous unipositive ion 3 of 10 What ions does it become with second ionisation Dipositive gaseous ion 4 of 10 3 factors dependent on ionisation energy shielding,distance,nuclear charge 5 of 10 Decrease from Be to B There an electron in the p sub shell higher energy level so less energy is needed 6 of 10 Decrease from N to O Electron removed from O is paired in the P sub shell which means there is slight repulsion between the electrons so less energy is needed 7 of 10 Which is the strongest bond? Giant covalent bond 8 of 10 Which group has the highest melting point 4 9 of 10 Why does group 4 highest MP Giant covalently bonded structure 10 of 10
