1.
No Bell work

3. 1. Name the three parts of an atom and where they are located.
a. Protons- inside Nucleus
b. Neutrons- inside Nucleus
c. Electrons- outside Nucleus in the Electron Cloud
2. What charge does each part of the atom have?
a. Protons...Positive +
b. Neutrons...No charge (Neutral)
c. Electrons...Negative -
3. What part of the atom is responsible for an atom’s ability to bond
with other elements?
Electrons

4. 3. What part of the atom is responsible for an atoms identity?
Protons
4. How do you know the number of protons an atom has?
Atomic Number
5. How do you know the number of electrons an atom has?
The # of electrons = the number of protons (Atomic Number)
6. How many electrons are in each energy level/shell?
1st level/shell - 2
2nd level/shell - 8
3rd level/shell- 18

5. 7. What is the atomic mass?
The mass of an atom; the # protons + # of neutrons
8. What parts of the atom account for the atomic mass?
protons & neutrons
 9. What is an isotope?
An atom that has the same number of protons but a different number of neutrons.
Are isotopes always the same element? Why?
Yes, they are the same element because they have the same number of protons.
11. Define periodic.
Repeated in a regular pattern or interval
12. What is the periodic table?
An aid used to describe and show properties of the known elements

6. 13. What are the three categories on the periodic table?
a. Metals
b. Metalloids
c. Nonmetals
14. How is the periodic table organized?
Into periods(rows) and groups(columns) based on the atomic number
15. What is the name of each group?
a. Group 1 Alkali Metals
b. Group 2 Alkaline Earth Metals
c. Group 3-12 Transition Metals
d. Group 13 Boron Group
e. Group 14 Carbon Group
f. Group 15 Nitrogen Group
g. Group 16 Oxygen Group
h. Group 17 Halogens
i. Group 18 Noble Gases

7. 16. How many electrons in the outer level/shell?
a. Group 1 – 1 electron
b. Group 2 – 2 electrons
c. Group 13 – 3 electrons
d. Group 14 – 4 electrons
e. Group 15 – 5 electrons
f. Group 16 – 6 electrons
g. Group 17 – 7 electrons
h. Group 18 – 8 electrons
17. What does the # of electrons in the outer energy level indicate
about the element?
It’s ability to form chemical bonds with other elements; it’s chemical
reactivity
