Question 1

These are called the building blocks of matter.

Answer 1

Atoms

Question 2

What is the most widely accepted model of the atom?

Answer 2

Niels Bohr’s planetary model.

Question 3

What are the three main types of elements?

Answer 3

Metals, Metalloids, and Non-Metals.

Question 4

How many valence electrons is the maximum amount an element can have?

Answer 4

8

Question 5

How do you determine the number of valence electrons an element can have?

Answer 5

The number of valence electrons of an element can be seen by counting the group number of the element in the periodic table from left to right. (Excluding transition metals)

(Also except helium, which has 2 valence electrons.)

Question 6

The atomic number of an element is the same amount as the number of protons and electrons it has. (Unless it’s an ion) True or False?

Answer 6

True

Question 7

These are the electrons on the outermost energy level of an atom.

Answer 7

Valence Electrons

Question 8

Atoms gain, lose, and share electrons to gain 8 valence electrons. What rule is this?

Answer 8

The Octet Rule

Question 9

Non-metals lose valence electrons. True or False?

Answer 9

False. They usually gain/receive electrons.

Question 10

Metals lose/give valence electrons. True or False?

Answer 10

True

Question 11

What do atoms become when they give/receive electrons?

Answer 11

Ions

Question 12

What is a pawsitively charged ion?

Answer 12

Cation

Question 13

What is a negatively charged ion?

Answer 13

Anion

Question 14

In giving valence electrons, the one with the least amount will give to the one with more, and the metal will give to the non-metal. True or False?

Answer 14

True

Question 15

Who created the Lewis Dot Structure?

Answer 15

Gilbert Lewis

Question 16

When doing the LEDS of an element, you should put one on all sides first before doubling the amount. True or False?

Answer 16

True

Question 17

Is the ability of an atom to ACCEPT one or more electrons.

Answer 17

Electron Affinity

Question 18

Is the ability of an atom to ATTRACT electrons.

Answer 18
