Name and give the symbol for each of the following:
a)the element in period 3 group 2
= Magnesium = Mg
b)the halogen in period 4
= Bromine = Br
c)the element in period 6 and group 11
= Gold = Au
d)the akali metal in period 2
= Lithium = Li
e)the noble gas in period 1
All right except for e. Hydrogen is not a noble element.
The noble gas in period 1 is not Hydrogen, so it would be Helium He. Sir, can you also take a look at my "Damon" post.
Just did the Damon post. He is correct for this one.
Thank you sir
