Question

1. which statement is true?

electrons are larger than protons. light orange
atoms are the smallest living organism. yellow
the number of protons in an atom determines the element. light purple

Explanation:

• Analyze each statement:
• Electrons have much smaller mass (and size - related to mass/volume) than protons. Protons are in the nucleus and have significant mass, while electrons are much lighter and smaller. So "Electrons are larger than protons" is false.
• Atoms are not living organisms. Living organisms are made of cells (the smallest unit of life), and atoms are non - living, fundamental units of matter. So "Atoms are the smallest living organism" is false.
• The number of protons in an atom's nucleus is the atomic number, and it determines the element. For example, all atoms with 6 protons are carbon atoms. So this statement is true.

Answer:

The statement "The number of protons in an atom determines the element" (the one with [light purple]) is true.
