Ans: Titanium

The distribution or arrangement of electrons in elements is represented in terms of electron configuration which depicts the electron occupation in various orbitals.

the s orbital has only one level and holds 2 electrons

p-orbitals have 3 sublevels and holds a maximum of 6 electrons

d-orbitals have 5 sublevels and holds a maximum of 10 electrons.

The element with two half filled orbitals in the ed sublevel must have an outer electron configuration of 3d²

Therefore, the inner electrons must be filled as follows:

1s²2s²2p⁶3s²3p⁶4s²3d²

The total number of electrons is 22. The element with the atomic number 22 is titanium (Ti)

What are the benefit of understanding physical properties?

klasskru [66]

Physical properties help identifying a substance and how it changes.
For example: if a substance crushes easily that means it has a low density, but if it’s hard and doesn’t crush easily, that means it has a strong high density.
And eventually the substance would not end up forming a new substance.
Look at the picture below to understand more about physical changes.
