How can there be both molecular and non-molecular solids?

Non-molecular solids are of the type of metallic and ionic solids. They are held together by the strong electrostatic interactions of polar particles like ions and electrons. For example in metals the strong...

In terms of electrons, explain the bonding in sodium chloride

Sodium is on group 1 and has 1 election in its outer shell. Chloride is in group 7 and has 7 electrons in its outer shell.Sodium looses 1 electron and chlorine gains 1 electron giving both atoms a full outer...

Why does ionisation energy decrease down group 2?

As you descend group 2, more electrons are present in the atom. These electrons fill subshells at a greater energy level. There is a greater distance between the outer shell electron and the nucleus, as well...

A student places equal masses of limestone rocks into two beakers. However, the student crushes the ones in one of the beakers to make a fine powder. Then, he adds hydrochloric acid to both of them. Which takes longer? Would one of them produce more CO2?

First of all let's think of which one would take longer. The one that would take longer would be the slower of the two reactions, and therefore would have a lower rate of reaction . So now we have to think: ...

What is the difference between ionic and metallic bonding?

Ionic bonds occur between a metal and non-metal. In this type of bonding, the electrons in the outer shell are transferred from the metal to the non-metal. This is to allow the atoms to achieve a full outer ...
