"Electronegativity is the power of an atom to attract the electron density in a covalent bond to itself"
In order to understand electronegativity we mu...

Graphite is made from layers of carbon which contain many 6-membered carbon rings (hexagonal). Each layer is held together by each carbon being covalently bonded to 3 other carbon atoms and this leaves a ...

Remember that ionisation energy is an endothermic process, in which energy from the chemical system is used to remove electrons from atoms in the GASEOUS STATE.

The atoms in an alloy are of different sizes so the layers are distorted and therefore, due to a lack of proper layers harder from them to slide over each other.

Carbon is the atom that makes up graphite. Carbon is in group 4 of the periodic table, this means that Carbon has 4 electrons in its outer shell. In graphite each Carbon atom forms three covalent bonds, t...
