Question: Write a short paragraph on how you separate mixtures at home?

We can separate mixtures at home by following ways;

Mixtures can be separated using a variety of techniques.

Chromatography involves solvent separation on a solid medium.

Distillation takes advantage of differences in boiling points.

Evaporation removes a liquid from a solution to leave a solid material.

Filtration separates solids of different sizes.

A strontium atom differ from a strontium ion in that the atom has a greater NUMBER OF PROTONS.
Every atom is made up of three particles, which are proton, neutron and electron. The proton and the neutrons are located inside the nucleus and they do not take part in chemical reactions, it is only electron that takes part in bond formation and chemical reaction.
Strontium has atomic number of 38, that means, it has 38 electrons, 38 protons and 38 neutrons.
Strontium has two electrons in its outermost shell, in order to attain octet form, strontium will donate these two electrons in a chemical reaction. By the time strontium donate two electrons, it will become a cation and has a charge of +2. At this state, strontium only has 36 electrons while the number of proton and neutron remain 38, thus, the atom has a greater number of protons.
