Answer:
Gold is much heavier than lead. It is very dense. Another rather simple way to think of this is that if the density of water is 1 g/cc then the density of gold is 19.3 times greater than water. Water weighs about 8.3 pounds per gallon.

Answer:
Absorbs energy
Explanation:
As an electron in an atom moves from the ground state to the excited state, the electron absorbs energy.
Electrons moves around in permissible orbits around the nucleus of an atom.
- An electron in a certain energy level has a definite amount of energy associated with it at that level.
- When an electron in ground state absorbs energy, it moves to a higher energy level.
- When an electron in excited state loses energy, it moves to a lower energy level.
The transition of electrons from one level to another involves loss or gain of energy.
Answer: Halogens tend to attract electrons when bonding (Option C)
Explanation: Halogens being non metals have greater electronegativities hence, attract electrons and making the statement disputed. Nobel gases are highly stable; this explains why they are nonreactive. They do not form chemical bonds because they only have a little tendency to either gain or lose an electron; on the other hand, halogens are reactive because they only need one additional electron to complete their octet.
