Because they make up everything!
Matter is all around you All tjjngs are made out of matter The table that you eat from has mass
why could Al fir through a permiable membrane? because the atom's radii was very small! hahahahahhahahhah....well that's a fact with a laugh thanks you v much u beeen a great crowd
SiO2 Please be a bit more precise. The composition of quartz is SiO2 which means that two atoms of oxygen share one atom of silicon. It can be described as "Silicon di-oxide," and as a result it forms long hexagonal crystals which may be surmounted with a six sided pyramid. On the Mhos scale of hardness it has a hardness of 7. Varieties of quartz include flint, amethyst, rose quartz etc. It also forms a massive variety which is often seen in metamorphic rocks, as a crystal in granites. In pure form it resembles clear glass. It has a conchoidal fracture.

yes
electron
the line spectrum of the hydrogen spectrum indicates that only certain energies are allowed for the electron of the hydrogen atom. In other words, the energy of the electron in the hydrogen atom is quantized.
The hydrogen atom has 1 electron.
an atom
The single electron in a neutral hydrogen atom resides in the 1s orbital.
hydrogen
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.
The hydrogen atom (1H) has only 1 proton and 1 electron (you probably think at this electron).
There is one electron in a hydrogen atom. Hydrogen has 1 valence electron and is therefore very unstable by itself. Hydrogen is diatomic, which means that it naturally occurs bonded with another Hydrogen atom: H2
One. A hydrogen atom contains only one electron, and it is a valence electron.
