Atomic Structure Flashcards
1
Q
For atoms of transition metals, the third shell is able to hold a maximum of how many electrons?
A
18
2
Q
What are isotopes?
A
Isotopes are atoms of the same element that have the same number of protons and electrons but different number of neutrons.
3
Q
Do isotopes have same chemical properties as its element? Why?
A
Yes. They have same number of electrons. Hence they will undergo the same chemical reactions to form compounds with the same chemical formula.

Q
Do isotopes have same physical properties as its element? Why?
A
No. Isotopes have a different number of neutrons, which means they will have slightly different masses. This will affect physical properties like their density.
