Accepted Answer

Proton

Question 5

Based on the periodic table in the fifth image, which of the following elements is considered a trace element?

Accepted Answer

Iron (Fe)

Question 6

Using the sixth image, what is the atomic number and mass number of a carbon atom with 6 protons and 6 neutrons?

Accepted Answer

Atomic number = 6, Mass number = 12

Question 7

Refer to the seventh image. How many electrons are in the second energy shell of an oxygen atom?

Accepted Answer

6

Question 8

The eighth image illustrates the octet rule. According to this rule, why are atoms with full valence shells less reactive?

Accepted Answer

Their outermost shell is stable and does not need to gain or lose electrons.

Question 9

Based on the ninth image, why is neon (Ne) chemically unreactive?

Accepted Answer

Its valence shell is full with 8 electrons.

Question 10

Using the tenth image, how many electrons does an oxygen atom need to fulfill the octet rule?

Accepted Answer

2

Question 11

Refer to the eleventh image. What is the average atomic mass of carbon, and why is it not a whole number?

Accepted Answer

12.011; because it is the weighted average of all carbon isotopes

Question 12

Based on the twelfth image, what is released when a radioactive atom decays?

Accepted Answer

Energy and particles

Question 13

The thirteenth image shows two real-world uses of radioactive isotopes. Which of the following is NOT a use of radioactive isotopes?

Accepted Answer

Accepted Answer

It contains 6 carbon, 12 hydrogen, and 6 oxygen atoms.

Question 15

The fifteenth image distinguishes between intramolecular and intermolecular bonds. Which statement is correct?

Accepted Answer

Intramolecular bonds occur within a molecule, while intermolecular bonds occur between molecules.

Question 16

Based on the sixteenth image, what type of bond is represented by the dashed line between two HF molecules?

Accepted Answer

Intermolecular bond

Question 17

Refer to the seventeenth image. What do the $$\delta^+$$ and $$\delta^-$$ symbols represent in the context of chemical bonding?

Accepted Answer

Partial positive and partial negative charges due to unequal electron sharing

Question 18

Based on the eighteenth image, which of the following is a type of noncovalent bond?

Accepted Answer

Ionic bond

Question 19
