Proton: positive charged particle, contained in atomic nucleus, mass=approx. 1 u
Neutron: neutral particle, contained in atomic nucleus, mass=approx. 1 u
Electron: negative charged particle, component of an atom (but not contained in nucleus), mass=approx. 1/1836 from the mass of a proton.

Does the carbon14 have more protons neutrons or electrons than carbon12?
It has the same number of protons and electrons, but two more neutrons.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Neutral atom with 53 protons in its nucleus would have how many electrons orbiting the nucleus?
For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
How are atoms the same?
they all have protons,neutrons,and electrons
Do protons nuetrons and electrons all have about the same mass?
Protons and neutrons have about the same mass, but electrons are much, much lighter.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
What three major parts of a atom?
The three constituents that make an atom are protons, neutrons, and electrons.
How many protons electrons and neutrons in chromium?
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
A neutral atom has the same number of protons as it does neutrons?
no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)
What atom has 11 neutrons 11 protons and 11 electrons?
none because the number of protons and electrons have to be the same.
