• transition metals

Anika, Elijah, and Avery are studying chemistry. They come across an element in their textbook. They are trying to figure out how many electrons are needed to make this element neutral. Can you help them?

• 4

• 8

• 16

• 32

Aria, Nora, and Emma are studying chemistry. They come across an element with the number 4. What does this number represent for the element?

• period number

• element name

• atomic number

• chemical symbol

Answer explanation

The number 4 represents the atomic number of an element in chemistry. Atomic number is the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. In this question, Aria, Nora, and Emma are studying an element with number 4 which implies it's the atomic number of the element.
