Why does the atomic radius decrease as you move along a period.

As you move along the period the proton number increases and the electrons are added to the same shell meaning no extra electron shielding occurs. Therefore the nuclear attraction to the outer most elect...

Why is Florine more electronegative than oxygen

Fluorine has 1 more proton than oxygen and one more electron but the same number of shells so no increased shielding. This means there is more electostatic attraction from the nucleus so increased pull fr...

What is hybridisation and how can it be used to explain the shapes of molecules?

Before we start on exploring the implications of hybridisation, we should start with a definition. Hybridisation can be thought of as the mixing atomic orbitals into new hybrid orbitals suitable that can ...
