getting ready to turn this in just want to check my answers any takers??
1. In an atom, electrons ____. (1 point)
are located in the nucleus
are paired with neutrons
are located in the electron cloud
are always in the same place
2. The maximum number of electrons in the second energy level of an atom is ____. (1 point)
two
four
eight
ten
3. The number of _____ is equal to the atomic number. (1 point)
protons
neutrons
electrons
both a and c
True or False
4. In an atom, an electron that is close to the nucleus is on the highest energy level. (1 point)
true
false
5. It is easier to move an electron from the outer energy level than from one closer to the nucleus. (1 point)
true
false
and what is your answers?
1. located in electron cloud
2. 8
3. protons
4. True. The closer the atoms are to the nucleus, the more energy it takes to move them between the levels.
5. True
3. The number of protons and number of electrons are equal for a neutral atom, therefore both.
4. When energy is ejected in the form of a radiated photon, the electron moves down in energy closer to the nucleus. The further the orbit is from the nucleus, the higher the energy level.
5. Sure. The closer the negative charge is to the positive charge, the harder it is to pull it away.
EDIT - Damon is right, for number 4.
What about 3 which I think is both a and c ?
Yeah, that is true. But the standard definition for the atomic number is the proton, since electrons can vary.

Sure! I would be happy to help you check your answers. Let's go through each question and find the correct answers together.
1. In an atom, electrons ____.
To find the correct answer, we need to know the basic structure of an atom. Electrons are negatively charged particles that orbit around the nucleus of an atom. Based on this information, we can determine that electrons are located in the electron cloud. Therefore, the correct answer is "are located in the electron cloud."
2. The maximum number of electrons in the second energy level of an atom is ____.
To find the correct answer, we need to recall the electron configuration rules. The second energy level can hold a maximum of 8 electrons. Therefore, the correct answer is "eight."
3. The number of _____ is equal to the atomic number.
To find the correct answer, we need to understand the fundamental properties of atoms. An atomic number represents the number of protons in the nucleus of an atom. Therefore, the correct answer is "protons."
4. In an atom, an electron that is close to the nucleus is on the highest energy level.
To find the correct answer, we need to understand the energy levels of electrons in an atom. Electrons closer to the nucleus have lower energy levels, while those further away have higher energy levels. Therefore, the statement is false, and the correct answer is "false."
5. It is easier to move an electron from the outer energy level than from one closer to the nucleus.
To find the correct answer, we need to consider the energy levels of electrons again. Electrons in outer energy levels are further from the positively charged nucleus and experience weaker attractive forces, making them easier to move. Therefore, the statement is true, and the correct answer is "true."
I hope this helps you check your answers accurately! Let me know if you have any other questions.
