What is the chemical symbol for Oxygen?
Og
O
On
Ox
Chemical symbols are one- or two-letter abbreviations derived from the elements English or Latin names. Oxygen is represented by the single letter O, which is universally recognized for this element. Other letter combinations like Ox or On are not valid symbols. Learn more at .
Which element has atomic number 1?
Helium
Hydrogen
Beryllium
Lithium
The atomic number of an element equals the number of protons in its nucleus. Hydrogen has one proton, giving it atomic number 1 and placing it at the very start of the Periodic Table. No other element has fewer protons. See details on .
In which group are the noble gases located?
Group 17
Group 1
Group 2
Group 18
Noble gases occupy the far right column of the Periodic Table, known as Group 18. They are unreactive due to having a full valence electron shell. This stability distinguishes them from other elements. More information is available at .
Which of these is a metal?
Chlorine
Sodium
Oxygen
Nitrogen
Sodium is an alkali metal located in Group 1 of the Periodic Table and exhibits typical metal properties like high conductivity and malleability. Oxygen, nitrogen, and chlorine are nonmetals and display very different chemical behaviors. For more, visit .
What is the approximate atomic mass of Carbon as shown on most Periodic Tables?
16
14
12
6
The atomic mass reported on the Periodic Table is a weighted average of all naturally occurring isotopes. Carbons average atomic mass is about 12.01, which is commonly rounded to 12 for simplicity. This reflects its dominant isotope, carbon-12. See the details at .
How many valence electrons does Sulfur have?
2
6
4
8
Sulfur is in Group 16 of the Periodic Table, and all group 16 elements have six valence electrons. These valence electrons determine sulfurs chemical behavior and bonding. The octet rule explains why sulfur often forms two bonds to reach eight electrons. More at .
Which element is located in Period 3 and Group 16?
Chlorine
Sulfur
Phosphorus
Argon
Periods run horizontally and Groups run vertically on the Periodic Table. Period 3 elements include sodium through argon. Group 16 contains oxygen, sulfur, selenium, etc. The intersection of Period 3 and Group 16 is sulfur. More info at .
Which property generally increases across a period from left to right?
Atomic radius
Metallic character
Atomic weight
Electronegativity
As you move left to right across a period, the nuclear charge increases while the electron shielding remains similar, pulling electrons closer to the nucleus and raising electronegativity. Metals on the left have low electronegativity, while nonmetals on the right have higher values. Atomic radius actually decreases in this direction. Learn more at .
Which element has the electron configuration [Ne] 3s 3p??
Silicon
Chlorine
Argon
Sulfur
The configuration [Ne] 3s 3p? corresponds to atomic number 17, which is chlorine. Neon core ([Ne]) accounts for 10 electrons, then 3s adds 2 and 3p? adds 5 more, totaling 17. Argon has 18 electrons, sulfur has 16, and silicon has 14. See .
Which of these is a transition metal?
Copper
Potassium
Calcium
Magnesium
Transition metals occupy the d-block of the Periodic Table, typically groups 3 through 12. Copper, found in group 11, is a classic transition metal with partially filled d-orbitals. Magnesium, potassium, and calcium lie in the s-block. Detailed info at .
What is the trend in atomic radius as you move down a group?
Decreases
Increases
Stays the same
First decreases then increases
Moving down a group adds electron shells, which outweighs the increase in nuclear charge, causing atoms to become larger. Each additional energy level places electrons further from the nucleus, expanding the atomic radius. This trend is consistent in all groups. Learn more at .
Which element in Period 4 exhibits an irregular electron configuration by having only one electron in its 4s orbital before filling the 3d subshell?
Iron
Potassium
Calcium
Chromium
Chromium has the configuration [Ar] 4s 3d? instead of [Ar] 4s 3d? due to extra stability from a half-filled d-subshell. This exception arises from electron correlation and exchange energy. Iron follows the expected pattern ([Ar]4s3d?). More at .

Study Outcomes

  1. Identify Element Symbols -

    Match each element's chemical symbol with its full name using periodic table practice problems designed for Grade 7.

  2. Recall Atomic Numbers -

    Memorize and retrieve atomic numbers for key elements when taking the periodic table quiz and reinforce your recall skills.

  3. Interpret Group and Period Trends -

    Analyze patterns in groups and periods to understand trends like atomic size, reactivity, and valence electrons on the periodic table for 7th graders.

  4. Apply Knowledge in Test Scenarios -

    Use your understanding of element properties to solve challenging questions in a periodic table test format with instant feedback.

  5. Evaluate Quiz Performance -

    Review instant results to identify strengths and weaknesses, track your progress, and focus on areas needing improvement.

  6. Compare Element Properties -

    Contrast physical and chemical properties of different elements based on their positions to deepen your grasp of element behavior.

Cheat Sheet

  1. Atomic Number & Element Symbols -

    Understanding that an element's atomic number equals its proton count is the first step in any periodic table practice problems set. 7th graders should also memorize common symbols like H (1), C (6), and O (8) to breeze through symbol-based questions. Try flashcards or the mnemonic "Happy Harry Cooks Onions" to strengthen recall and confidence.

  2. Periodic Trends: Atomic Radius & Ionization Energy -

    In a periodic table quiz, you'll often see arrows showing trends: atomic radius decreases across a period while ionization energy increases. This happens because additional protons pull electrons closer, boosting nuclear attraction (American Chemical Society). Practice by marking trend arrows on blank tables to lock in the pattern.

  3. Metal, Nonmetal & Metalloid Zones -

    Classifying elements into metals, nonmetals, and metalloids is a staple in any periodic table test. Remember the zigzag staircase line: elements left of it are metals, right are nonmetals, and along it are metalloids like silicon and boron. Drawing the zigzag on your periodic table gives a quick visual guide for practice problems.

  4. Valence Electrons & Group Numbers -

    For periodic table practice problems, knowing that a main-group element's group number equals its valence electrons is key to predicting reactivity. For example, group 2 elements have two valence electrons, making them eager to lose electrons and form +2 cations. Use the phrase "Valence Equals Group" to cement this rule before your quiz.

  5. Isotopes & Average Atomic Mass -

    Some periodic table quiz questions ask you to calculate average atomic mass using isotopic abundances, like chlorine's ³❵Cl and ³❷Cl isotopes. Apply the formula (mass₝×abundance₝ + mass₂×abundance₂) to find an average, then compare with the listed atomic mass on the table. Practicing these calculations helps you ace isotopic problems with confidence.
