The elements that react very vigorously with water and air are immersed in mineral oil....But mg is not so reactive so it doesn’t react with water and oxygen in air so it’s not put in mineral oil...

In finely divided forms Magnesium is easily ignited. It burns with an intense white flame. It can also cause skin irritation. And so you must not touch it with your hands.

why does the reactivity increase as you go down the graph

@mal2215 5 жыл бұрын

this is because, nuclear charge increases AS WELL AS number of shielding electrons therefore, the dominant factor is the more energy levels and so the electrons are further away from the nucleus therefore it is easier for electrons to come off. so we can say Na is more reactive than Li since it is easier to remove electrons.

@pasijutaulietuviuesas9174 4 жыл бұрын

Each period adds a new layer of electrons, so the last 2 electrons become further and further away from the nucleus which makes them easier to separate from the nucleus so they react more down the group. Reaction depends on exchange of electrons. Easier to gain or lose an electron? Now reactive.

@JesseDNME 4 жыл бұрын

This is because the electrostatic attraction between the nucleus and the outermost electrons " valence electrons" as you go down the group weakens so they can " fall" off easily so making the reaction faster

@adiliraliyev5882 4 жыл бұрын

Is it too much to ask to explain why the elements in group 2 are more dense, reactive, softer going down the group? Think it would be easier to understand the periodic table rather than just memories the facts, also would be more useful in life....I think so anyways.
