Answer:
9
3
1
Explanation:
The correct question can be seen in the image attached.
a) The number of orbitals in a shell is the square of the principal quantum number(n). Hence, the number of orbitals present at n=3 is 3^2 =9.
b) n=5, l=1 suggests a 5p sublevel. This sub-level has a total of three degenerate p orbitals, px, py and pz.
c) n= 5 l=3, ml=3 refers to one of the seven degenerate 5f orbitals.
Answer:
The law says the sum of all forms of energy is constant :)
The mass is the protons+neutrons and the atomic number is just how many protons there are

Explanation:
The hypothesis is the proposed explanation for a scientific problem.
The control is the quantity in an experiment in an experiment that remains unchanged.
The empirical evidence is the data or facts that can be observed.
The dependent variable is the variable that changes in response to experimentation.
The independent variable is the experimental factor that is changed by the scientist.
