Answer:
It's because of the presence of protons.
Explanation:
A nucleus of an atom has protons and neutrons. We know that a proton has a charge of
+
1
, while a neutron has no charge, or
0
. Therefore, the nucleus of an atom will always have a positive charge.
Answer:
A piece of gold foil was hit with alpha particles, which have a positive charge. Most alpha particles went right through. This showed that the gold atoms were mostly empty space. Some particles had their paths bent at large angles. A few even bounced backward. The only way this would happen was if the atom had a small, heavy region of positive charge inside it.
c) positively charged and relatively small.
Answer:
The Periodic Table organizes chemical elements according to the number of protons that each has in its atomic nucleus
Its basically a chart with all the known elements on it. The elements are organized by period and group. Period and group are determined by the number of protons and electrons an atome has.
