A covalent bond is formed because electrons are being shared.
Orbital interactions with each other produce bonding. Single covalent bonds occur when 2s orbitals overlap and combine around the nucleus.
covalent hope i helped :)
The 2s orbital looks much like the 1s orbital except that the electron is more likely to be found further from the nucleus. The bonds that are formed are called the Sp3 bond and the Sp2 bond.
Electrons in a bonding orbital have lower energy levels than the average energy of a valence electrons in the isolated atoms between which the orbital is formed. Antibonding orbitals do not meet this criterion, so that anitbonding orbitals can be stable only in conjunction with bonding orbitals, whereas bonding orbitals can be formed without any accompanying antibonding orbitals.The molecular orbitals which is formed by the addition of atomic orbitals is called bonding molecular orbitals.The molecular orbitals which is formed by the subtraction of atomic orbitals is called antibonding molecular orbitals.
According to the molecular orbital theory, Beryllium containes 4 electrons and two orbitals. However, when two atoms combine, they produce four orbitals and eight electrons. Therefore, for every bond formed, there will be an anti-bond created.
Hybridization of atomic orbitals is the intermixing of atomic orbitals having a approximate energy to form equal number of hybrid orbitals having the same shape, size and energy but pointing in different directions. The new orbitals which are formed are "hybrids" of the originals and have properties that are somewhere in between. For example, a common hybridization is sp3 where three p orbitals combine with an s orbital to form four new orbitals. Other combinations (such as sp and sp2) are also possible.
Sigma bonds (single bonds) are formed as a result of the overlapping of s orbitals.
hybrid orbital
A covalent bond is formed when two nonmetals combine.
atoms combine to give molecules
He said that compounds are formed when atoms of different elements combine
An alloy
