Answer:
Orbital Notation is more specific on where exactly the electron is placed.
Explanation:
When writing an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all the core electrons together and designate it with a symbol of the corresponding noble gas on the Periodic Table.
the arrangement of electrons in the orbitals of an atom or molecule
While Orbital Notation is a visual transformation of the electron configuration. It shows you where each specific electron is placed and what its "spin" is.

A. Chemical energy transforms into electrical and sound energy. Hope this helps I had this question not to long ago
Answer is 0.10 mol.
<em>Explanation;</em>
n = m/M
Where n is number of moles (mol), m is the mass of substance (g) and M is the molar mass of the substance (g/mol).
n = ?
m = 0.40 g
M = 4.0 g/mol
From substitution,
n = 0.40 g /4.0 g/mol
n = 0.10 mol
Hence, the balloon has 0.10 mol of He.
