Atomic radius is the distance from the nucleus to the last valance electron up to which the effect nucleus can be felt. The size of the atom depends on the Electrostatic interaction between nucleus and electron. Number of atomic orbitals present. With the increase in numbers of orbitals down the group the size of the atom increases. Again, as the numbers of electrons increases in the period ,the electrostatic interaction between nucleus and electron increases along the period. Therefore, size of atoms decreases along the period.
As expected the element with highest atomic radius is the last element of group 1 , Which is FRANCIUM ( Fr)
Answer:
Option d)3.32 g is correct.
Explanation:
hope this helps
<span>Three atoms can be connected to the carbon atom with sp2 hybridization of a molecule.As sp2 hybridization for three sp2 hybrid orbitals which can only be connected to three other atoms.As an example is the ethene molecule(C2H4) which have 2 Carbon atoms with sp2 hybridization and one Carbon atom is connected with two hydrogen atoms and one carbon atom.</span>
Answer:
sub-particle charge mass
protons +1 1
neutron 0 1
electron - 1 negligible
protons and neutrons are found in the nucleus
electrons in the shells orbiting the nucleus
