What is the bond order of li2−? express the bond order numerically?
jeka94
Atomic Number of Lithium is 3, so it has 3 electrons in its neutral state. Also, Li₂ will have 6 electrons. But the chemical formula we are given has a negative charge on it (i.e Li₂⁻) so there is an additional electron (RED) present on this compound. So, the total number of electrons are 7. The MOT diagram for this compound is shown below. According to diagram we are having 4 electrons in Bonding Molecular Orbitals (BMO) and 3 electrons in Anti-Bonding Molecular Orbitals (ABMO). Bond Order is calculated as,

              Bond Order  =  (# of e⁻s in BMO - # of e⁻s in ABMO) ÷ 2

              Bond Order  =  (4 - 3) ÷ 2

              Bond Order  =  1 ÷ 2
Or,
              Bond Order  =  1/2
Or,
              Bond Order  =  0.5

What is defined as the number of atoms surrounding an atom in a crystal lattice?
Simora [160]

Answer:

coordination number

Explanation:

Coordination number -

In a crystal lattice , the number of atoms that are surrounded to a particular atom , is referred to as the coordination number of the crystal.

In the field of crystallography and chemistry , it is also called the ligancy.

In coordination chemistry , the number of ligands attached to the central metal atom is also known as the coordination number of the coordination compound.

Hence, from the given statement of the question,

The correct term is coordination number.
