Question

1. Atoms can get excited in the following ways: A) Getting bashed by a high speed electron B) Absorbing a photon with energy that matches an electron transition between allowed energy states C) Absorbing a photon of any energy D) A and C E) A and B

2. When an atom is in an excited state: A) All electrons are in a higher energy state than in the ground state B) The lowest energy electron state is not occupied C) Usually just one electron is in a higher energy state than in the ground state. The other electrons remain in their ground state arrangement. D) All electrons have enough energy to escape from the attractive positively charged nucleus E) Something else

3. When an atom is in its ground state: A) All the electrons are occupying the same lowest energy state B) Electrons are located inside the nucleus C) All the electrons are occupying the lowest energy states of atom with a max of 2 electrons per state

Explanation / Answer

1. Atoms can get excited in the following ways:
A) Getting bashed by a high speed electron : True
B) Absorbing a photon with energy that matches an electron transition between allowed energy states : True
C) Absorbing a photon of any energy : False. Energy must be grater than the difference
D) A and C
E) A and B

Answer: E
