The general trend for a substance's heat capacity and atomic mass is that they are inversely proportional. This is because denser or larger atoms have particles that are closer to each other. The close proximity of these particles make it easier to transfer heat because of their increased vibration, making the heat capacity required smaller.
B) ionic. Generally, metals and non-metals form ionic bonds that are stronger than covalent bonds due to the higher electronegativity difference.
Answer:
The halogens are extremely reactive, whilst the noble gases are mainly inert.
Only some noble gases tend to form compounds, such as xenon and krypton. However, some like helium, almost have no compounds at all.
Noble gases also have octet rule shells, which causes the little reactivity associated with them.
To form bonds with noble gases, a lot of energy is required to form those bonds.
Halogens, on the other hand, are extremely reactive. Compounds like chlorine and fluorine must be stored carefully, as they will oxidise anything that they can find, just to get one extra electron to get an octet configuration.
Hope this helps :)
Answer:
21
Explanation:
Formula;
Mass number = number of protons + number of neutrons
= 9 + 12
= 21
Answer:
it would be an alloy
Explanation:
It is a type of substance that is made by the melting of two or more elements together.
