WebBond Length is the average distance between the two nuclei of atoms bonded together in a covalent bond. It is affected by bond order and atomic radius. As bond length increases, bond energy decreases due to an inverse relationship between the two. As bond order increases, the atoms are pulled closer together and bond length decreases. WebThis means that the nucleus attracts the electrons more strongly, pulling the atom's shell closer to the nucleus. The valence electrons are held closer towards the nucleus of the atom. As a result, the atomic radius decreases. Nuclear charge increases due to protons NOT electrons. Greater number of electrons doesn't increase the strength of the ...

WebApr 9, 2024 · The periodic trend of atomic radius across a period – As we move from left to right in a period, atomic radius gradually decreases. Reason – As we move left to right in a period the atomic number of the elements increases so nuclear charge increases while the number of shells in elements remains the same. Example –.
