The results of rutherford's gold foil experiment gave him the evidence to arrive at two conclusions: (1) an atom was much more than just empty space and scattered electrons and (2)

a) in any atom, electrons orbit a central nucleus.
b) all atoms were composed of three subatomic particles.
c) an atom must have a positively charged center that contains most of its mass.
d) an atom must have an equal number of positive and negative particles in a central location.

The answer to your question is: letter C

Explanation:

A) in any atom, electrons orbit a central nucleus.

B) all atoms were composed of three subatomic particles.

C) an atom must have a positively charged center that contains most of its mass.

D) an atom must have an equal number of positive and negative particles in a central location.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
