Question

for the following, play around with the simulation to answer the following questions. some questions may be answered using your data collected in part 1 or from class notes. 1. what particle(s) are found in the center of the atom? what particles are found outside of the center of the atom? 2. which particle(s) determines the name of the element you build? 3. create atoms based on the values given below. what are the names for the following atoms? (hint: found in the center of the atom model) a. an atom with 3 protons and 4 neutrons: b. an atom with 2 protons and 4 neutrons: c. an atom with 4 protons and 4 neutrons:

Explanation:

1. The nucleus, at the center of the atom, contains protons and neutrons. Electrons are found outside the nucleus in electron - shells.
2. The number of protons in an atom determines the element's identity. Each element has a unique number of protons (atomic number).
3. a. An atom with 3 protons is lithium as the atomic number (number of protons) of lithium is 3.

b. An atom with 2 protons is helium since the atomic number of helium is 2.
c. An atom with 4 protons is beryllium as the atomic number of beryllium is 4.

Answer:

1. Protons and neutrons are in the center; electrons are outside.
2. Protons.
3. a. Lithium

b. Helium
c. Beryllium
