The electron configuration of calcium is 1s2 2s2p6 3s2p6 4s2. There are four rings of electrons around the nucleus and there are two electrons in the first ring, eight in the second ring, eight in the third ring and two in the fourth ring. This makes 20 electrons and therefore there will also be 20 neutrons and 20 protons present in the nucleus.
Here are some other basic facts about where calcium is placed in the periodic table;
It was discovered as an element in 1808 by Humphrey Davy in London, England. At this time it was referred to as calcis or lime and it as found to be present in many rocks.
Calcium is incompatible with water, acids, air chlorine fluorine, oxygen, silicon and sulphur. It breaks down and reacts when mixed with these substances.
There is also calcium in our bodies. On average, there is 1kg in every 75kg human being. This calcium is naturally occurring but it is also taken in through our diet. Plants that are grown in soil that contains calcium will have levels of calcium in them and animals also have calcium in them as we do and when we eat dairy or meat, this is transferred to us.
It is recommended that we eat calcium as it is nutritious.
