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.
What else can I help you with?
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
How are atoms the same?
they all have protons,neutrons,and electrons
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
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.
What particle control the 'weight' of an atom?
The weight of an atom is primarily controlled by the total number of protons and neutrons in its nucleus. Protons and neutrons have approximately the same weight, while electrons have negligible mass compared to protons and neutrons.
An atom has what number of protons and electrons?
9 protons and 10 neutrons in F-19 isotope.
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.
What do Atoms of the same element have same atomic?
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
What element is composed of atoms with the same number of neutrons or protons?
Ideally, all elements should have the same number of protons, neutrons and electrons unless they become ionic. This is how elements such as the noble gases remain stable. They the same number of electrons, protons, and neutrons, and a full octet.
How many protons neutrons and electrons are in Rutherfordium?
Rutherfordium has 104 electrons and 104 protons. The number of neutrons is between 149 and 264, depending on the isotope.
