Question

1. in the simulator, experiment by adding each type of particle to your atom. based on this, which particle determines the name of the element? what element is it? - create the following atoms, then answer the questions on the right. particles what element is it? protons: 7 neutrons: 7 electrons: 7 protons: 7 neutrons: 8 electrons: 8 protons: 8 neutrons: 7 electrons: 7 5. did the identity of the element change when the number of neutrons and electrons was changed? 6. did the identity of the element change when the number of protons was changed? 7. open the tabs titled

et charge\ and \mass number.\ now add additional protons, neutrons, and electrons to the last atom you created. which of these particles affects the mass of the atom? 8. re - create a basic nitrogen atom with 7 protons, neutrons, and electrons. each of the dotted - line circles are called energy levels. are both energy levels used in an atom of nitrogen? 9. in a neutral atom of nitrogen, how many electrons are in the inner energy level? 10. in a neutral atom of nitrogen, how many electrons are in the outer energy level? 11. continue to add more electrons to the nitrogen atom until there are none left. what is the maximum number of electrons can be held in the outer energy level? 12. when additional electrons are added to a neutral atom of nitrogen, what changes?

Explanation:

1. The number of protons determines the name of an element as it defines the atomic number.
2. Changing the number of neutrons and electrons does not change the element identity as long as the proton - number is the same. Neutrons affect isotopes and electrons affect charge.
3. Changing the number of protons changes the element identity because the atomic number changes.
4. Protons and neutrons affect the mass of the atom as they are located in the nucleus and have significant mass compared to electrons.
5. In a nitrogen atom, both energy levels are used.
6. In a neutral nitrogen atom, 2 electrons are in the inner energy level.
7. In a neutral nitrogen atom, 5 electrons are in the outer energy level.
8. The maximum number of electrons in the outer energy level is 8.
9. When additional electrons are added to a neutral nitrogen atom, it becomes a negatively - charged ion.

Answer:

1. Protons
2. No
3. Yes
4. Protons and neutrons
5. Yes
6. 2
7. 5
8. 8
9. It becomes a negatively - charged ion.
