✔ 最佳答案
a. isotopesb. 1
c. chemical reactions involves only the outermost electrons of atoms, not the nucleus. as deuterium has the same electronic configuration as hydrogen, they will react in same way.

a. They are isotopes (因為佢地 atomic number 一樣)
b. 1 (比 hydrogen 多一粒neutron , 唯一結構上分別)
c. Chemical reactions usually involves the numeber of outermost shells electon ,
As hydrogen and deuterium have same proton , they have same number of
outermost electrons , also same electronic configuration , in normal condition.
So , they carry out same reaction.

a.Isotope
b.1
c.Isotopes have the same chemical properties but ifferent physical properties, so reaction towards oxygen is the same.
b.1
c.Isotopes have the same chemical properties but ifferent physical properties, so reaction towards oxygen is the same.
