Which particle or particles make up the nucleus?
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.
What is the basic particle from which elements are made?
An atom is the basic particle from which elements are made :D
Why is it impossible for helium or hydrogen to emit an alpha particle?
Because an alpha particle is bigger than a helium or hydrogen atom.
How is a element is different from a compound?
Elements can be broken down into smaller pieces: a compounds smallest particle is a molecule
What is the element with the most mass per nucleon?
The element has the lowest mass per nuclear particle is Iron, while hydrogen is the element with the highest mass per nuclear particle. Cause "nuclear particle" here means particles forming nucleus, like proton or neutron. Hydrogen has just one proton, and an atomic mass of 1.00794, it's mass per nuclear particle is also 1.00794. For heavier elements like Iron, they have higher atomic mass but also more particles in their nucleus. For instance, iron has 26 protons and 30 neutrons, and an atomic mass of 55.847, it's mass per nuclear particle should be 55.847/(26+30)<1, which is much smaller than that of hydrogen.
Why hydrogen gas will diffuse fastest?
This is because hydrogen is the smallest size particle out of all elements and therefore easier to diffuse in a substance eg. air.
Which particle or particles make up the nucleus?
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.
Are elements different?
Elements are the basic building blocks for anything. Elements are made up of atoms which are the smallest pieces of matter that retain identification by element. In a nutshell meaning if you were to break down an atom into subatomic particles the particles are not different then one another if they are the same type of particle. Atoms are anything from hydrogen to aluminum to cobalt or even xenon. Elements are different according to how many protons that they have (In atoms there are equal protons and electrons).
How are atoms and elements different?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle

Is hydrogen the smallest particle of an element?
An average hydrogen atom consists of 1 proton and 1 electron. The 1 proton accounts for nearly all of that atom's mass. The 1 electron has only about 1/2000th the mass of the proton. That's about 0.0005 of the total atomic mass.
What is the smallest particle of hydrogen?
A single atom of hydrogen-1 is the smallest particle of hydrogen. A hydrogen-1 atom contains only one proton and one electron, and is the simplest atom.
Why is it impossible for helium or hydrogen to emit an alpha particle?
Because an alpha particle is bigger than a helium or hydrogen atom.
Why are protons and neutrons used in the subatomic particle?
Protons and neutrons provide the mass of an atom. Each different kind of element has a unique number of protons. For example: all hydrogen atoms have one proton. However, not all hydrogen atoms have the same mass. Some hydrogen atoms have no neutrons, one neutron, or two neutrons. Atoms of the same element (one proton) but different numbers of neutrons (different masses) are called isotopes of that element. All elements have isotopes. Some isotopes of elements are radioactive and are useful in medicine and energy applications (nuclear, for instance).
