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).

True or false all matter is made of atoms?
Technically false, because of the words "spin around". That's not how elecgtrons really work. They exist as spherical standing probability functions. If that's what you meant by "spin around", then yes, it's true.
The small central part of an atom?
The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
The central atom in PH3 is surrounded by?
A PH3 molecule has a triangular pyramidal shape. The central atom is the Phosphorus atom, which is connected to three Hydrogen atoms.
Which is a true statement about the atomic nucleus. It takes up most of the volume of the atom. It contains protons neutrons and electrons. It contains most of the mass of the atom?
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.
What is the central atom found in CFClBr2?
CARBON
When an atom gains electrons it becomes positively charged true or false?
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?
true
True or false the atom is the simplest unit of an element?
true
True Or False most of an atom's volume is the space in which electrons move?
True, most of an atom's volume is the space in which electrons move.
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
True or false a atom is ionized if one of its electrons jumps to a higher energy level in the atom?
Flase ============== Answer #2: Phalse ------------------------------------------------------------------------------------------ Answer number 3 (with no jokes): False. An atom is ionised only when an electron completely leaves the atom.
When an atom gain an electron its becomes a positive ion true or false?
false
The nucleas of an atom is much larger than the atom yet contains most of its mass true or false?
true
Rutherford measures the weight of an atom for the first time true or false?
True
The idea of an atom has been around for only about 200 years true or false?
false.
True or false a sodium atom tends to lose one electron when it reacts?
True.
What is the central of an atom is called?
nucleus
