D. The volume of a new substance has increased.
The average atomic mass of the element is 204.40 amu
<h3>Average atomic mass and isotopic mass</h3>
- The average atomic mass of an element is the average mass of the atom of that element calculated from the isotopic masses of the atoms of that element and their percentage abundances
- Isotopic mass is the mass of each isotope of that element
<h3>Calculation of average atomic mass</h3>
Average atomic mass = sum of isotopic mass * abundance of each isotope
Average atomic mass = 202.99 * 29.524% + 70.476% * 204.99 amu.
Average atomic mass = 204.40 amu
Therefore, the average atomic mass of the element is 204.40 amu

Answer:
6
Explanation:
The maximum number of electrons in the orbitals of sub-levels are given as:
for s-sublevel we have two electrons and one orbital
p-sublevel we have six electrons and three orbitals
d-sublevel we have ten electrons and five orbitals
f- sublevel we have fourteen electrons and seven orbitals
The second energy level is represented by the p-sub-level and it will accommodate 6 electrons.
Answer:
The sum of the protons and neutrons.
Explanation:
protons + neutrons = atomic mass
