WebView Lanthanoid Contraction.pdf from MATHS 1A at Cambridge. Meta Title: Lanthanoid Contraction Meta Description: Lanthanide Contraction is a term used to describe the atomic radius trend observed in 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. duty of care as a student nurse

How does atomic radius decrease

Weband the atomic radius decreases. You might expect the atomic radius to increase because the number of electrons in each atom increases going across period 3. However, this does not happen: the number of protons also increases and there is relatively little extra shielding from electrons in the same shell. 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 ...
