Which element is least likely to undergo a chemical reaction?
2 answers:
The elements least likely to undergo a chemical reaction are:
Gold: Au
Silver: Ag
Platinum: Pt
They are located very low in The Reactivity Series and hence don't react with any other substance. That is why their market value is pretty high.
Answer:
Helium
Explanation:
Helium is most likely to undergo a chemical reaction because
- It has a complete electron shell, so it does not need any more electrons
- Its electrons are closest to the nucleus, so it is extremely difficult to remove them

Answer:
mass of Mg=0.016g
Explanation:
P(Mg)=1.7g/cm³
P(Fe)=7.9g/cm³
m(Fe)=819g
P(Fe)=m(Fe)/v(Fe)
7.9=819/v(Fe)
v(Fe)=0.0096cm³
since v(Mg)=v(Fe)
=0.0096cm³
P(Mg)=m(Mg) /v(Mg)
1.7=m(Mg)/0.0096
m(Mg) = 0.016g
