Calcium is in group 2 period 4 of periodic table
Oxygen is in group 16 and period 2
neon is in period 2 and group 16.
Explanation:
Valence electron in calcium =2
valence electron in oxygen= 6
valence electron in neon= 8 valence electron.
Calcium is placed in s block group 2 of period 4.
oxygen is placed in period 2 and group 16
Neon is a p block element, placed in period 2 and group 16.
Calcium is a elecropositive element which can share or donates its electrons to for compound, it has oxidation state of +2 and hence placed in group 2
Oxygen is electronegative as it can accept or share 2 electrons to form a bond. It has oxidation of -2.
Example is CaO.
Neon has its outer shell complete it is an inert element which will not share or donate electrons. it has oxidation state of 0
The southeast has flat lands, rich soil,and long growing seasons which has made it a center for food processing.
C would be the correct answer
Answer:
Plutonium and Uranium are elements that are found in the actinide series of the periodic table. They are different from each other in several properties as discussed in this article above. The main difference between Plutonium and Uranium is that Plutonium is highly radioactive whereas Uranium is weakly radioactive.
