What can be determined if only the atomic number of an atom is known?
(1) the total number of neutrons in the atom, only
(2) the total number of protons in the atom, only
(3) the total number of protons and the total number of neutrons in the atom
(4) the total number of protons and the total number of electrons in the atom

The wave shown on the electromagnetic spectrum disturb the medium it passes through a)different frequency. b)the same frequency .

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
