Question
The number of unpaged electrons m the outer sub-shell of it chlorine (Cl) atom is 0 1 2 3 None of these Atomic Size/Ionic Size/Ionization Energies Indicate which atom or ion in each of the following pairs that you would expect to be larger by size (atomic radius) by picking for the first choice or for the second choice Li or (b) Be O or (b) O^2- Fe or (b)Fe^3+ H or (b) H^- Which of the following elements has the LARGEST first ionization energy?^15 P^6 C^19 K^12Mg^18 Ar Consider the ionization energy (IE) of the magnesium atom Which of the following is not true The IE of Mg is lower than that of sodium The IE of Mg is lower than that of neon The IE of Mg is lower than that of beryllium The IE of Mg is higher than that of calcium The IE of Mg is lower than that of Mg^2+Explanation / Answer
option b is correct answer
25.
atomic number is 17
1s2 2s2 2p6 3s2 3p5
3p5 means P have three subshells
so 4 electrons as pair and one unpaired electron
option b is correct answer
