Answer is: group 17 on the periodic table.
Group 17 (halogens) elements are: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).
They are very reactive and easily form many compounds.
Fluorine and chlorine are in gaseous state, bromine is liquid and iodine is in solid state in room temperature.
Halogens need to gain one electron to have electron cofiguration like next to it noble gas.
For example, fluorine has 9 electrons and it gain easily one electron in chemical reaction to have electron configuration like noble gas neon (Ne) with 10 electrons.

Overlap of two p atomic orbital produces oxygen gas ,o2 because it has two unpaired electron and explains paramagnetism.
O2 molecules have two unpaired electrons Materials in which all the electrons are paired are diamagnetic. It repel a magnetic field.Para magnetic and diamagnetic materials do not act as permanent magnets. Molecular orbital theory provides an explanation of chemical bond that explains paramagnetism of the oxygen molecule. It also explains the bonding in a other molecule. O2 molecule has two unpaired electron. Electrons creates magnetic field as it goes to the ground state and also spin.MO theory describes the distribution of electrons in molecules same as the distribution of electrons in atoms described using atomic orbital.

Answer:
in all green plants and most algae
The energy transferred is 28.5 j
<em><u>calculation</u></em>
energy is calculate MCΔT formula where,
M(mass)= 6.30 grams
C(specific heat capacity)= 0.377 j/g
ΔT(change in temperature)= 32.0c- 20 c= 12 c
Energy is therefore= 6.30 g x 0.377 j/g /c x 12 c =<u>28.5 j</u>
