Electrons are:

A) able to move from one atom to another; the atom that loses an electron becomes positively charged and the atom that gains an electron becomes negatively charged

B) charged particles that move freely between all atoms; when an atom loses an electron it becomes negatively charged

C) negatively charged and can move between atoms; the atom that loses an electron becomes negatively charged and the atom that gains an electron becomes positively charged

D) positively charged particles that when transferred between different atoms create ions that are positively charged

The answer to your question is: letter A

Explanation:

A) able to move from one atom to another; the atom that loses an electron becomes positively charged and the atom that gains an electron becomes negatively charged This is the correct answer to your question, because describe characteristics of electrons.

B) charged particles that move freely between all atoms; when an atom loses an electron it becomes negatively charged. This option is wrong because when an atom loses an electron it becomes positive, so this answer is wrong.

C) negatively charged and can move between atoms; the atom that loses an electron becomes negatively charged and the atom that gains an electron becomes positively charged. This answer is wrong because it says that an atom that loses and electron becomes negatively charge and vice versa.

D) positively charged particles that when transferred between different atoms create ions that are positively charged This answer is incorrect because electrons are negatevely charged.

A) is the correct answer
