Sketch a periodic table, and label the areas containing elements that give rise to the three types of hydrides.
1 answer:
The periodic table is a table of the chemical elements organized by atomic number, from the element with the lowest atomic number to the element with the highest atomic number.
The table consists of various hydrides.
Hydrides are the compound of hydrogen with a more electropositive element or group.
They are less electronegative elements than as compared to other elements.
Hydrogen molecule normally reacts with all elements except noble gases to form hydrides. There cannot be any noble gas hydride.
There are differing type of hydrides:
- Ionic hydrides
- Covalent hydrides
- Metallic hydrides
Ionic hydrides are formed when hydrogen molecule reacts with highly electropositive s-block elements. It consists of alkaline and alkaline earth metals.
Example: calcium hydride (CaH₂).
Covalent hydrides are formed when hydrogen reacts with other similar electronegative elements. The compound shares a covalent bond within the molecule and are either a volatile or non-volatile compound.
Example: Methane (CH₄).
A hydrogen compound that forms a bond with another metal atom is classified as a metal hydride.
Example: Aluminium (Al).
