Answer:
when they have eight valence electrons.
Explanation:
When atoms do not have a full valence shell, the atoms are more likely to react with other and vice versa.
Answer:
4687.5 mL
Explanation:
Given that the density of the substance = 8.96 g/mL
Mass = 42.0 kg
The conversion of kg into g is shown below as:
1 kg = 1000 g
So, mass = 42.0 × 1000 g = 42000 g
Volume = ?
So, volume:
The volume of the 42.0 kg of the substance = 4687.5 mL
<span>Radioactive waste, as its name implies, is a source of radiation that can be harmful to living organisms. Therefore it needs to be disposed of very carefully in such a way that the radiation cannot reach human beings and other living organisms. One method to do this is to bury the waste in deep pits. </span>
