Group 15 hydride

So imagine you have a group of elements called group 15. These elements like to react with hydrogen gas to form a special kind of molecule called a hydride. When we talk about a group 15 hydride, we are referring to one of these special molecules that is made up of an element from group 15 (like nitrogen or phosphorus) and hydrogen.

Now, imagine you are playing with building blocks. These blocks are like the elements. When you put certain blocks together, they stick to each other and form a new shape. This is like how the elements stick together to form a molecule.

The group 15 hydride molecules have a very important job – they can help to make other chemical reactions happen. They are called "reducing agents" because they can help to turn other molecules into smaller ones by adding a hydrogen atom. This is kind of like adding another block to your building creation to make it smaller.

In summary, a group 15 hydride is a special molecule made up of an element from group 15 (like nitrogen or phosphorus) and hydrogen. It is important because it can help to make other chemical reactions happen by adding a hydrogen atom to a molecule, kind of like adding another block to make a creation smaller.
