Calcium has 2 valence electrons and tends to lose these electrons to achieve a stable electron configuration with a full outer shell. When reacting to form compounds, calcium typically loses 2 electrons, resulting in a stable 2+ cation. This allows calcium to achieve an electron configuration similar to a noble gas, following the octet rule by having a full outer shell of 8 electrons.
Calcium typically forms ionic bonds. As a group 2 metal, calcium readily donates its two valence electrons to achieve a stable octet configuration, forming the Ca2+ cation. This cation then forms ionic bonds with other ions or compounds.
Xenon can achieve a stable octet by forming compounds with elements that can share their electrons with xenon. For example, xenon can form compounds with fluorine, chlorine, or oxygen where xenon acts as the central atom and bonds with these more electronegative elements to complete its octet.
Yes, lithium (Li) and calcium (Ca) can form ionic compounds. Lithium has a +1 charge, and calcium has a +2 charge, so they can combine to form compounds like lithium chloride (LiCl) or calcium fluoride (CaF2) through ionic bonding.
No, BCl3 does not follow the octet rule as boron only has 6 valence electrons in this molecule. Boron can form stable compounds with less than an octet due to its electron deficiency.
Calcium Carbonate
Sodium and calcium form the cations Na+ and Ca(2+).

Calcium cannot form a covalent compound because it is a metal, covalent compounds are formed only from non-metals.
Uranium typically forms compounds where it does not have an octet due to its ability to expand its valence shell beyond eight electrons. Uranium can often exceed the octet rule in its bonding arrangements.
Boron typically forms compounds by sharing electrons, rather than obtaining a full octet. It can form compounds with elements such as hydrogen and fluorine, but it often displays unique bonding patterns due to its electron deficiency.
No, BCl3 does not follow the octet rule as boron only has 6 valence electrons in this molecule. Boron can form stable compounds with less than an octet due to its electron deficiency.
There is a general tendency to form an octet, to have a stable structure.
No, xenon does not always follow the octet rule. It is a noble gas and can form stable compounds that have more than eight electrons around the xenon atom, known as expanded octet.
