Atomic Structure Quiz

Which of the following is true of metal elements?

• They are dull.

• They are good conductors.

• They have a full valence electron level.

• They are brittle.

Which of the following statements is the BEST and MOST ACCURATE answer to the following question: Characteristic properties of an atom are determined how?

• The characteristic properties of an atom is determined by the number of electrons because they are determined by the atomic mass number.

• The characteristic properties of an atom is determined by the number of neutrons since it determines the number of electrons.

• The characteristic properties of an atom is determined by the number of protons since they determine the number of valence electrons.

One of the characteristic properties of this type of element is that it is a semiconductor.
