Yes, many particles are lighter than atoms. Subatomic particles, such as electrons and neutrinos, have much smaller masses compared to atoms. For example, an electron has a mass of about 1/1836 that of a proton, which is a major component of Atomic Mass. Thus, several fundamental particles are indeed lighter than atoms.
Electrons are the particles of an atom that have little mass compared to protons and neutrons. Electrons are around 1836 times lighter than protons and neutrons.
quark
Neutron ?
Far more complex.
An iron atom is the smallest iron particle that still has the properties of iron.
Electrons are the particles of an atom that have little mass compared to protons and neutrons. Electrons are around 1836 times lighter than protons and neutrons.
quark
It is an atom. More specifically, it would be a cation - which is an atom which has "lost" one or more electrons and so is less than an atom.
neutron
A neutron.
The smallest particle of an element is called an atom.
Basically, atoms are made up of subatomic particles. Subatomic, sub- meaning smaller that, so subatomic particles means "a particle smaller than an atom". So It means that it is a particle within the atom.
An atom is a particle, the smallest particle that can exist by itself.
Yes, a particle can be a single atom.
A quark is a fundamental subatomic particle, or class of subatomic particles. It is smaller than an atom.
Of course it is smaller. It is a sub atomic particle
