The protons and neutrons of all atoms are made up of the smallest known particles of matter called what?
Protons and neutrons are made of up and down quarks
Which part of Dalton's theory did Thomson's findings dispute?
The atom is the smallest known particle.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The central part of an atom that contains protons and neutrons?
nucleus
What is the number of protons neutrons in radium?
Does atom is the smallest particle?
No, atom is not the smallest particle. Atoms are not even particles, but elements. Atoms are made up of 3 particles: Electrons, Protons, and Neutrons. The protons and neutrons are made up of even smaller particles known as quarks.
What particle is a helium nucleus and consists of two protons and two neutrons?
a He nucleus is known as alpha particle.
The protons and neutrons of all atoms are made up of the smallest known particles of matter called what?
Protons and neutrons are made of up and down quarks
Which part of Dalton's theory did Thomson's findings dispute?
The atom is the smallest known particle.
What is the smallest particle in quantum physics?
QUARKS are the smallest particles.they r known to be smaller than electrons,neutrons and protons.discovered way back in the 20th century
Particle with a large mass and a posiive charge?
A particle that has a large mass and a positive charge is known as an alpha particle. These particles contain 2 protons and 2 neutrons which are bound together to form an identical particle to a helium nucleus.
What is smaller in terms of size than an atom?
Subatomic particles are smaller than atoms. Subatomic particles are found inside the nucleus of an atom and include protons, neutrons, quarks, and gluons. Protons carry a positive electrical charge while neutrons carry a neutral charge. Inside these protons and neutrons are quarks which are held together by gluons. (1 atom = 0.000000001 meters while 1 quark = 0.000000000000000001 meters) The smallest known particle, however, that has mass is the neutrino.
Is the atom the smallest possible object?
at the moment, the smallest thing in the universe known to man is the neutrino, with a mass of less than 0. this is the opposite of an electron. electrons are one of the three main things that make up atoms.
Can you list particles from smallest to greatest mass?
electrons are the lightest then protons then neutrons
Particle found in nucleus?
The main constituents of the nucleus are protons and neutrons, but each of these is made up of smaller particles known as quarks.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What does atom mean?
Atoms are the smallest particle there is and can't be broken down any further. Atoms consist of protons and neutrons in the nucleus and electrons in the electron cloud also known as orbitals and shells. Atoms are the building blocks of everything, they make everything everywhere, dead or alive.
