In an atomic model that includes a nucleus, positive charge is a
concentrated at multiple sites in an atom.
b
concentrated in the center of an atom.
c
spread evenly throughout an atom.
d
located in the space outside the nucleus.

Acamcorder has a power rating of 17 watts. if the output voltage from its battery is 7 volts, what current does it use?units:

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.

How might this scientific phenomena be explained? a paper clip floats on water.
