Answer : Option C) Atomic orbitals overlap to form molecular orbitals in which the valence electrons of the atoms travel.
Explanation : The band theory in the metallic bonding can be explained by the combination of atomic orbitals to form molecular orbitals in which the valence electrons of the different or same atoms travels to form molecular bonding.
It can be bonding or anti-bonding, depending on the availability of the electrons coming from the atoms of elements.

Answer:
The answer should be, B, The periodic table
Answer:
<h3>The answer is 7.5 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 5 mL
density = 1.5 g/mL
We have
mass = 1.5 × 5
We have the final answer as
<h3>7.5 g</h3>
