Atomic Structure

Question 1

For atoms of transition metals, the third shell is able to hold a maximum of how many electrons?

Answer 1

18

Question 2

What are isotopes?

Answer 2

Isotopes are atoms of the same element that have the same number of protons and electrons but different number of neutrons.

Question 3

Do isotopes have same chemical properties as its element? Why?

Answer 3

Yes. They have same number of electrons. Hence they will undergo the same chemical reactions to form compounds with the same chemical formula.

Question 4

Do isotopes have same physical properties as its element? Why?

Answer 4

No. Isotopes have a different number of neutrons, which means they will have slightly different masses. This will affect physical properties like their density.
