Test - Atomic Structure Flashcards
1
Q
- Each family in the periodic table has its own characteristics properties based on the number of…
A
Valence Electrons NB Pg. 7
2
Q
- What is the greatest number of valence electrons an atom can have?
A
8 NB Pg.14
3
Q
- The atomic number of magnesium is 12. Therefore it’s nucleus must contain…
A
12 protons and no electrons NB Pg.7
4

A
9 neutrons and 8 electrons NB Pg.8
5
Q
- The total number of electrons in the outer shell of a sodium atom is…
A
1 NB Pg.16
6
Q
- Which particles determine the atomic number of an element?
A
Protons only NB Pg.8
7
Q
- Which of the following elements would be the best conductor of electricity?
A
Silver NB Pg.14
8
Q
- Solid Sphere Model; elements are atoms with different masses.
A
John Dalton NB Pg.3
9
Q
- Nuclear Model; Gold Foil experiment allowed him to discover that the nucleus was the positively charged center of the atom surrounded by negatively charged electrons.
A
Ernest Rutherford NB Pg.3
10
Q
- In each period, how does the number of electrons in each kind of atom change from left to right between groups 1 and 2? Explain how you know.
A
Atoms electrons increase by one because protons increases by one. NB Pg.7
11
Q
- Describe one similarity and one difference between the two atoms you drew above. Include why each difference and similarity is expected, based on each elements location on the periodic table.
A
The number of valence electrons are the same so they are in the same group. The number of energy levels is different so they are in different periods. NB Pg.16
12
Q
52b. This element has 6 energy levels and 8 valence electrons. It must be (blank).
A
Radon NB Pg.16
13
Q
- Classify the following elements as metals, nonmetals, or metalloids. Include one characteristic/property of each type.
A
Tellurium = Metalloid, semi conductors. NB Pg.15
