In ______ bonding, the valence electrons are shared among all the atoms of the metallic elements.

Q. Give a single term for the following statements:
a) The tendency of atoms to have eight electrons in the outer shell.
b) Energy required to remove a valence electron to have an isolated atom.
c) The pair of electrons that are not involved in bond formation.
d) Tendency of an atom to attract bonded pairs of electrons towards itself in a molecule.
e) Bonds in which shared electron pair comes from one of the bonded atoms.

Q. (a) What is the number of valence electrons in the atoms of first elements in a period?
(b) What is the usual number of valence electrons in the atoms of the last element in a period?

Q.

Across a period, the electrons are filled in the __ valence shell of all elements.

Q. In metallic bonding, the ‘sea of electrons’ that are accumulated from all the metal atoms act as a ‘glue’ between all the metal ions holding them together. What constitutes this ‘sea of electrons’?

Q.

What are the terms defined in (i) and (ii) below?
(i) A bond formed by a shared pair of electrons, each bonding atom contributing one electron to the pair.
(ii) A bond formed by a shared pair of electrons with both electrons coming from the same atom.
