sp2 Hybridization. The valence orbitals of a central atom surrounded by three regions of electron density consist of a set of three sp2 hybrid orbitals and one unhybridized p orbital.
<h3>How do you describe hybrid orbitals?</h3>
A hybrid orbital is an orbital formed by the combination of two or more atomic orbitals. The resulting orbital has a different shape and energy than the component orbitals that form it. Hybridization is used to model molecular geometry and to explain atomic bonding.
<h3>What is the hybridization of the s atom?</h3>
The middle S atom containing the 5 valence atomic orbitals is basically hybridized to form five sp3d hybrid orbitals. In 2P-orbitals, four hybrid orbitals are overlapped and the fifth one contains a lone pair.

Answer: a. alpha emission : atomic number decreases by 2 units and mass number decreases by 4 units.
b. beta emission : atomic number increases by 1 unit and mass number remains same.
c. gamma emission : atomic number and mass number both remain same.
Explanation:
1. Alpha emmision: In this process, alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units, thus atomic number decreases by 2 units and mass number decreases by 4 units.
2.)Beta-emmision: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units, thus atomic number increases by 1 unit and mass number remains same.
3.) Gamma ray emission: in this process, an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and releases . These radiations does not carry any charge and are electrically neutral, thus atomic number and mass number both remain same.
