False. An alpha particle is equivalent to a helium-4 nucleus.
false
False. Water is a molecule made of 2 parts hydrogen one part oxygen. NOT AN ELEMENT.
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.
The pH scale is a Science indicator, Not a Mathmatical one :-)
I'm not really sure if it's called a HUB, but I do know that the central core of an atom is called the nucleus, and is made out of protons (with a positive charge) and neutrons (with no charge).
Correct, due to the massive size of the gold nucleus compared to the size of the incoming particle, the particle will not experience a large deflection in a head-on collision. This is because of the concentrated positive charge in a small space in the gold nucleus that causes a very strong Coulomb repulsion when the incoming particle gets close to it.
Yes it is true. In fusion reactions, two nuclei (not necessarily be hydrogen) combine to form a larger nucleus.

Assuming the context of this question is atomic physics, the answer is "false" for two reasons: 1) the atomic nucleus is positively charged. 2) the atomic nucleus a tightly bound composite of many particles.

False and why
False, it is in the center of the cell
At its most basic all matter is made up of various quarks. Quarks come in six flavours as both quarks and antiquarks. They form electrons, protons and neutrons. These larger particles form the atoms of all elements.
False. Hydrogen is the most abundant element in the universe, constituting about 75% of its elemental mass.
False!!
