An element is composed of atoms with the same number of?
Neutrons.
What types of particles are protons and neutrons and electrons?
protons,neutrons are very tiny particles that are found in the atoms.
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).
What do neutrons consist of?
Neutrons consist of small particles, called "Quarks". Protons also consist of quarks, but what quarks is made of, is still not discovered.
How much neutrons does molybdenum have?
Most molybdenum atoms have 54 neutrons. The atomic number (number of protons) of molybdenum is 42, and its weight (number of protons and neutrons) is around 96. 96 - 42 = 54.
What did Einstein discover about atom?
Einstein discovered that atoms had protons and neutrons.
Who discovered that atoms were composed of protons and neutrons?
neutrons were discovered by james chadwick by an experiment which was started by madam curie. protons were discovered by rutherford in his alpha ray scattering experiment
Who said atoms contain neutrons?
James Chadwick discovered the neutron in 1932.
Neutrons have been called nuclear glue because... why?
The presence of neutrons in nuclei allows the strong force to overcome the electrostatic repulsion between protons. If it weren't for the presence of neutrons, there would be no atoms in the universe other than hydrogen.
How long has it been that scientists have accepted that the nucleus of the atom consists of neutrons and protons?
Ernest Rutherford discovered protons in the nuclei of atoms in 1918, and James Chadwick discovered neutrons in 1932.
What part of Dalton's theory of was disproved when scientists discovered that atoms contain protons electrons and neutrons?
John Dalton believed that atoms were the fundamental building blocks of matter, and that they could not be created, destroyed or split. However he was wrong, because atoms are made out of subatomic particles such as Protons, Neutrons and Electrons - and later still, it was discovered Protons and Neutrons too are made of even smaller particles.
Thomson discovered that atoms were not simple spheres but contained what?
protons and neutrons. atoms are not the smallest thing but protons are. protons are slightly smaller than neitrons. but are not simple sphere's.
Did bohr discover that the atoms mass came frome neutrons and protons?
Rutherford discovered that almost entire mass of an atom is located in the nucleus, and then, the neutron was discovered by Chadwick.
Who discovered atomic neutrons?
James Chadwick discovered neutrons in 1932.
Are neutrons in the atoms of different elements alike?
neutrons of all atoms are alike
Protrons and neutrons are these?
Protons and neutrons are subatomic particles found in the nucleus of atoms (with the exception of hydrogen atoms, which have no neutrons).
What are atoms of the same element but with different masses?
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
