Periodic Table Quiz

QUESTION 1: Which of these is NOT one of the basic pieces of an atom?

Electron Quantron Proton Neutron

CORRECT! There is no atomic particle called a quantron. Neutrons, protons, and electrons are all basic pieces of an atom.

QUESTION 2: Which atomic particles will you find inside of the nucleus of an atom?

Electron and Proton Proton and Neutron Neutron and Electron

CORRECT! Protons and neutrons are located in the nucleus of an atom. Electrons orbit the nucleus.

QUESTION 3: Which atomic particle has a negative charge?

Electron Proton Neutron None of the Above

CORRECT! Electrons are the atomic particles with the negative charges. Protons have a positive charge and neutrons have a neutral charge.

QUESTION 4: An electron has a mass that is much less than a proton.

True False

CORRECT! Electrons are incredibly small compared to both protons and neutrons. Both neutrons and protons are over 1,000 times larger than an electron.

QUESTION 5: An atom with a neutral charge has the same number of...

Protons and Neutrons Neutrons and Electrons Protons and Electrons

CORRECT! A neutral charge would mean equal amounts of positive and negative charges. Equal amounts of protons and electrons would create an atom with a neutral charge.

QUESTION 6: The innermost atomic shell can hold a maximum of 18 electrons.

True False

CORRECT! The innermost atomic orbital can only hold two electrons. The next orbital can only hold eight electrons.

QUESTION 7: When atoms bond with each other, they exchange...

Protons Neutrons Electrons

CORRECT! When atoms bond, they exchange electrons. Atoms that donate and receive electrons form electrovalent bonds. Atoms that share electrons are in covalent bonds.

QUESTION 8: About how many known elements are there?

10 50 100 200

CORRECT! There are about 110 known elements listed in the periodic table. As scientists continue to experiment they will be able to make more elements.

QUESTION 9: Elements in the periodic table are arranged by...

Atomic Number Atomic Weight Number of Neutrons Chemical Reactivity

CORRECT! The elements of the periodic table are organized by atomic number. Hydrogen and helium make up the top row of the periodic table at numbers one and two. The atomic number represents the number of protons and electrons in a neutral atom.

QUESTION 10: Which scientist came up with the concept of a periodic table that included all of the known elements?

Jason Priestly Dmitri Mendeleev Antoine Lavoisier Albert Einstein

CORRECT! Dmitri Mendeleev is credited with designing the modern periodic table.

QUESTION 11: The atomic number of an element tells you the number of _____ in a neutral atom.

Positrons Neutrons Electrons None of the Above

CORRECT! The atomic number of an element tells you the number of electrons and protons in a neutral atom.

QUESTION 12: What is the first element on the periodic table?

Helium (He) Hydrogen (H) Lithium (Li) Argon (Ar)

CORRECT! Hydrogen (H) is the first element on the periodic table. It has only one electron and one proton. It is also the most abundant element in the entire universe.

QUESTION 13: Sulfur's (S) contains 16 electrons. It’s electron configuration is...

2-16-16 2-8-6 1-6-15 2-6-8

CORRECT! Sulfur (S) is the sixteenth element in the periodic table. That means a neutral sulfur atom has 16 electrons. Using the 2-8-8 rule... Sulfur would have a setup of 2-8-6.

QUESTION 14: Which of these choices is not a major part of an atom?

Electrons Protons Neutrons All are parts of an atom

CORRECT! All of these particles are found in atoms. Hydrogen is a little special because it does not have a neutron, but all of the other elements have varying numbers of electrons, neutrons, and protons.

QUESTION 15: An ion is a form of an atom with a different number of...

Electrons Protons Neutrons All of the Above

CORRECT! Ions are atoms with different numbers of electrons when compared to neutral atoms of the same element. You will often see ions with values of + or -.
