Question

1. label the diagram of the atom below using the provided word bank.

proton neutron electron electron shell/orbit
a. __________
b. __________
c. __________
d. __________
(diagram with labels a, b, c, d)

1. complete the following fill in the blanks with the same word bank.

a. subatomic particles called __________ are negatively charged and found in the orbits of an atom.
b. __________ are subatomic particles found in the nucleus and carry a positive charge.
c. __________ are the location in which an electron is found within an atom.
d. __________ do not have an electrical charge and are found in the nucleus of an atom.

1. on the periodic table every element has an atomic number, symbol, name, and atomic mass number.

a. what does the atomic number represent?
b. what does the atomic mass number represent?

1. fill in the table below with the correct element names and symbols from the periodic table.

(table with symbol, element name, symbol, element name; rows: cl, c, o, n; and potassium, silver, fluorine, aluminum)

Explanation:

1. Atom diagram labels use the word bank: Proton (nucleus, + charge), Neutron (nucleus, no charge), Electron (orbit, - charge), Electron Shell/Orbit (electron location).
2. Subatomic particles: Electrons are negative in orbits; Protons positive in nucleus; Electron Shell/Orbit is electron location; Neutrons neutral in nucleus.
3. Atomic number = proton count; Atomic mass number = protons + neutrons.
4. Element symbols/names: Cl=Chlorine, C=Carbon, O=Oxygen, N=Nitrogen; K=Potassium, Ag=Silver, F=Fluorine, Al=Aluminum.

Answer:

1. a. Proton, b. Neutron, c. Electron, d. Electron Shell/Orbit
2. a. Electron, b. Proton, c. Electron Shell/Orbit, d. Neutron
3. a. The number of protons in an atom, b. The sum of protons and neutrons in an atom
