Double Bonds A Double bond is when two atoms share two pairs of electrons with each other. It is depicted by two horizontal lines between two atoms in a molecule. This type of bond is much stronger than a single bond, but less stable; this is due to its greater amount of reactivity compared to a single bond.
When electrons are shared between two atoms, they make a bond called a covalent bond. Because two atoms are sharing one pair of electrons, this covalent bond is called a single bond. The bonding electron pair makes the covalent bond.
What is it called when two atoms share electrons?
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
When atoms share pairs of electrons they form?
Covalent bonds A covalent bond is formed when two atoms share a pair of electrons . Covalent bonding occurs in most non-metal elements , and in compounds formed between non-metals.
Why do electrons come in pairs?
It is due to the fact that even though electrons have negative charge they are bound to the nucleus by the attraction force from the nucleus and thus they have to somehow be around the nucleus and at the same time be in the lowest possible energy situation.
What happens when two chlorine atoms bond?
The two chlorine atoms are said to be joined by a covalent bond. The reason that the two chlorine atoms stick together is that the shared pair of electrons is attracted to the nucleus of both chlorine atoms. Hydrogen atoms only need two electrons in their outer level to reach the noble gas structure of helium.
Can two atoms share more than one pair of electrons?
1) Covalent bonds are formed between atoms through simultaneous ‘sharing’ of electrons. 2) More than one pair of electrons can be shared between atoms to form double or triple covalent bonds.
