Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration for Hafnium with atomic number of 72 and containing 72 electrons is:

$1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^24d^{10}5p^66s^24f^{14}5d^2$

The electronic configuration for Hafnium in terms of nearest noble gas Is

$[Xe]6s^24f^1{14}5d^2$

The mass of a diamond that has a volume of 0.35cm3

MAXImum [283]

Answer:

1.225g

Explanation:

From the question given,

Volume of diamond = 0.35cm^3

Density of diamond = 3.5g/cm^3

Mass of diamond =?

Density = Mass /volume

Mass = Density x volume

Mass = 3.5 x 0.35

Mass of diamond = 1.225g
