Question

In a chemical combination, atoms combine to form molecules by _________ from a metallic atom to a non-metallic atom.
A) Sharing of valence electrons.
B) Transfer of valence electrons.
C) Losing electrons.
D) Gaining electrons.

Answer 1

Hint: We know that Metallic solids are formed by metal atoms and they have metallic bonding present in them. We can classify the solids into two types which are crystalline and amorphous in which the atoms in crystalline solids have well-defined arrangement while in amorphous solids does not have well-defined arrangement.

Complete step by step answer:
Solids can be classified into four types namely,
Molecular solids: The van der Waals forces, hydrogen bonds, or both cling to most of the atoms or small molecules in molecular solids.
Covalent network solids: If all the atoms are held in position by covalent bonds then the solid is called covalent solid.
Ionic solids: If oppositely charged ions are detained together by very strong electrostatic attractions, comparable in strength to covalent bonds is called ionic bond.
Metallic solids: The solids which are formed by metal atoms and the metals which have metallic bonding in them are called metallic solids.

In a chemical combination, atoms combine to make molecules by transfer of valence electrons from a metallic atom to a non-metallic form.

Therefore, the option B is correct.

Note:
Now we discuss about the concept of intermolecular forces and the types of intermolecular forces as,
Intermolecular forces: Intermolecular forces are electrostatic forces and comprise van der Waals forces and hydrogen bonds. Molecules in liquids are detained together by intermolecular connections, which are weaker than the intramolecular connections that hold the atoms jointly within molecules and polyatomic ions. The greater the intermolecular forces, greater will be the melting and boiling point.
The three major types of intermolecular interactions are,
Dipole-dipole interactions
London dispersion forces
Hydrogen bonds
