Understanding the periodic table gives us a good way of understanding the elements in science. Each element is differentiated by another due to its components and number of items. The quiz below was created to test out a student’s understanding of the atoms and the elements in the periodic table. Why don’t you give it a try and see just how much you recall from your classwork?

• 1.

### Which two part of the atom have about the same mass?

• A.

Electrons and shells

• B.

Protons and neutrons

• C.

Orbits and protons

B. Protons and neutrons
Explanation
Protons and neutrons have about the same mass in an atom. Protons are positively charged particles located in the nucleus of an atom, while neutrons are neutral particles also found in the nucleus. Both protons and neutrons have a mass of approximately 1 atomic mass unit (AMU), which is about 1.67 x 10^-27 kilograms. Electrons, on the other hand, have a much smaller mass and are located in energy levels or shells surrounding the nucleus. Therefore, the correct answer is Protons and neutrons.

### The number of protons is the same as the number of electrons which is the same as _____

• A.

The atomic weight

• B.

The atomic number

• C.

The Peroidic family

B. The atomic number
Explanation
The atomic number of an element represents the number of protons in its nucleus, which is also equal to the number of electrons in a neutral atom. Therefore, the statement "The number of protons is the same as the number of electrons which is the same as the atomic number" is correct.

### There are  __________ number of elements in the current periodic table

• A.

About 111, but I have not checked Google today to see if a new one was found.

• B.

More than 100 but after that I am a little lost

• C.

Less than 100

• D.

A whole bunch but I am not sure how many, can I go look at the chart?

A. About 111, but I have not checked Google today to see if a new one was found.
Explanation
The correct answer states that there are about 111 elements in the current periodic table, but the person is unsure if a new element has been discovered today as they have not checked Google.

### Protons have a  ________________ charge

• A.

Pleasing

• B.

Negative

• C.

Neutral

• D.

Positive

D. Positive
Explanation
Protons have a positive charge because they contain positively charged particles called quarks. These quarks have a positive electric charge, which results in the proton having an overall positive charge.

### The first orbital of an atome can hold

• A.

8 electrons

• B.

2electrons

• C.

6quarks

• D.

4zippos

B. 2electrons
Explanation
The first orbital of an atom can hold a maximum of 2 electrons. This is because the first orbital, also known as the 1s orbital, has a spherical shape and can accommodate a maximum of 2 electrons due to its low energy level. The Pauli exclusion principle states that each electron in an atom must have a unique set of quantum numbers, including spin, and therefore, only two electrons with opposite spins can occupy the 1s orbital.

### A full outer shell of an atom is called

• A.

A full ring

• B.

A full octet

• C.

A stable octet

• D.

A chubby atom

C. A stable octet
Explanation
The full outer shell of an atom refers to when the outermost energy level is completely filled with electrons. This state is known as a stable octet. A stable octet is achieved when there are eight electrons in the outermost energy level, except for hydrogen and helium which only require two electrons to achieve stability. This configuration provides the atom with a balanced charge and makes it less likely to form chemical bonds with other atoms, resulting in a more stable and inert state.

### If there are 2 electrons in the first ring and 3 in the second ring, what element are we talking about?  ( run  to the periodic to look real quick)

• A.

Carbon

• B.

Nitrogen

• C.

Boron

• D.

Neon

C. Boron
Explanation
The element we are talking about is Boron. This is because Boron has an atomic number of 5, which means it has 5 electrons. The electrons are arranged in energy levels or shells around the nucleus. The first energy level can hold a maximum of 2 electrons, and the second energy level can hold a maximum of 8 electrons. Since there are 2 electrons in the first ring and 3 in the second ring, it matches the electron configuration of Boron.

### If an atom has 6 electrons in it's outer shell it will want to....

• A.

Give up electrons to become stable

• B.

Gain or take electrons from another element to become stable

B. Gain or take electrons from another element to become stable
Explanation
When an atom has 6 electrons in its outer shell, it is considered to be unstable. In order to achieve stability, it will try to gain or take electrons from another element. This is because atoms tend to follow the octet rule, which states that atoms are most stable when their outermost energy level is filled with 8 electrons. By gaining or taking electrons from another element, the atom can achieve a full outer shell and become stable.

### The term we use when talking about the weight (mass) of an atom is

• A.

An Emu ... energy mass unit

• B.

An Amu ... atomic mass unit

• C.

Watts

B. An Amu ... atomic mass unit
Explanation
The term we use when talking about the weight (mass) of an atom is an Amu, which stands for atomic mass unit. This unit is commonly used in chemistry and physics to express the mass of atoms and molecules on a very small scale. It is defined as 1/12th the mass of a carbon-12 atom. The atomic mass unit allows scientists to compare the masses of different atoms and calculate molecular weights accurately.

### WHen talking about atomic models is goes in this order

• A.

Dalton's atom model, the gold foil and then plumpudding

• B.

Plum pudding, gold foil and then Dalton's model

• C.

Dalton's atom, Thompson's plum pudding and then Rutherford's gold foil

• D.

Moe, larry, curly

C. Dalton's atom, Thompson's plum pudding and then Rutherford's gold foil
Explanation
The correct answer is Dalton's atom, Thompson's plum pudding, and then Rutherford's gold foil. This is the correct chronological order of the atomic models discussed. Dalton's atom model was proposed first, followed by Thompson's plum pudding model, and then Rutherford's gold foil experiment led to the discovery of the nucleus.
