19
Q

The ratio of naturally occurring chlorine-35 to its isotope chlorine-37 is 3:1. What is the standard atomic weight of chlorine?

20
Q

A student represents electrons within the same orbital as having parallel spins. This goes against which principle?

A

Pauli exclusion principle

21
Q

The maximum number of electrons in a shell with principle quantum number (n) of 4 is:

A

32 electrons

2)(4)(4

22
Q

In Bohr’s model of the hydrogen atom, the energy of an electron is dependent on:

A

The principle quantum number (n)

This is because the equation for energy of Bohr model is:

E = -Rh / n^2

23
Q

What describes the excitation exhibited when an electron jumps from its ground state to a higher energy level?

A

Atomic absorption spectrum

24
Q

The Pauli exclusion principle states that

A

No two electrons can have the same quantum number

25
Atoms with the same atomic numbers but different mass numbers are known as
Isotopes
26
