Which of the following pairs correctly matches the element to its symbol and group?

K – Potassium – Alkali Metal

Ne – Neon – Alkaline Earth Metal

A student is given the symbol "Br". Which family does this element belong to, and what is its typical reactivity?

Transition Metal, moderate reactivity

Which of the following elements is most likely to form a $$+1$$ ion and why?

Sodium, because it is in Group 1

Oxygen, because it is in Group 16

Neon, because it is in Group 18

Magnesium, because it is in Group 2

A student claims that all elements in Group 18 are gases at room temperature. Use your knowledge of the periodic table to evaluate this claim.

The claim is incorrect; some Group 18 elements are solids at room temperature.

The claim is correct; all Group 18 elements are gases at room temperature.

The claim is incorrect; all Group 18 elements are liquids at room temperature.

The claim is incorrect; all Group 18 elements are metals.

Given the elements Lithium (Li), Sodium (Na), and Potassium (K), explain why they are placed in the same group and predict a property they share.

They are all Alkali Metals and react vigorously with water.

They are all nonmetals and are unreactive.

They are all Halogens and form diatomic molecules.

They are all Noble Gases and are inert.

If you are given the symbols "Na", "Mg", and "Al", arrange these elements in order of increasing atomic number and identify their respective groups.

Na (Group 1), Mg (Group 2), Al (Group 13)

Al (Group 13), Mg (Group 2), Na (Group 1)

Mg (Group 2), Na (Group 1), Al (Group 13)

Na (Group 2), Mg (Group 1), Al (Group 13)

A student is asked to predict which element, Fluorine (F) or Iodine (I), is more reactive. Using your understanding of periodic trends, select the correct answer and justify it.

Fluorine, because reactivity increases up the group for halogens.

Iodine, because reactivity increases down the group for halogens.
