2) Draw a complete Bohr-Rutherford diagram showing all the parts of the atom for 14 N 7, 33 S 16, 40 Ca 203.a) Number 1 is an alkali Metal b) Number 8 is a Halogen c) Number 2 is an alkaline earth metald) Number 9 and 10 are noble gassese) elements in period 4 are transition elements. 3.B) 4,6,7,8,9,10 are non metals.4) The order for decreasing atomic radius is: Na, Si, C Sodium and carbon have the smallest atomic radius than silicon. And carbon has the smallest atomic radius since it is placed in period 2. 5) The decreasing order for ionization energy is: F, N, P Since ionization energy decreases going down, I know that phosphorus is last. Nitrogen comes before fluorine when going across the row. Going across the row the nuclear charge increases.
