What is the electron configuration of:C+O+Ne-Al+S+Ga+Plz help
Carbon 6 electrons, so we have 1s2 2s2 2p2 It has a 1+ charge so it has one electron missing so that's 1s2 2s2 2p1Oxygen 8 electrons, so we have 1s2 2s2 2p4, it has a charge of 1+ so it is missing one electron so it is 1s2 2s2 2p3 Neon is a noble gas so it is unusual to find it ionised but the normal atom looks like this: 1s2 2s2 2p6 which is stable and it doesn't want to ionise but Ne- should look like this 1s2 2s2 2p6 3s1 as it has one extra electronAluminium will fill up as follows: Al 1s2 2s2 2p6 3s2 3p1, since it has a positive charge we knock off one electron from the outer shell 1s2 2s2 2p6 3s2 Sulfur again the atom looks like this: 1s2 2s2 2p6 3s2 3p4, it has a charge of 1+ so we knock one electron off 1s2 2s2 2p6 3s2 3p3 Gallium looks like this: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p1 so the 1+ ion will lose the 4p1 electron and look like this: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 Hope that helps.
