How many protons electrons and neutrons does Si-29 has?
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
Do all things have the same number of electrons protons and neutrons?
no some have 5 and 6 or more
The parts of an atom?
Well there is protons, electrons, and neutrons. Protons and neutrons are in the nucleus and the electron i outside revolving around it. The number of them depends on what periodic element specifically.
What is an atom and what does it consist of?
An atom is the smallest amount of an element that still retains that element's properties. An atom is made up of protons, neutrons, and electrons. Protons have a positive charge, and are part of the nucleus. Neutrons have no charge, and are part of the nucleus as well. Electrons have a negative charge, and orbit the nucleus. Scientists also believe that protons and neutrons are made up of quarks.
An atom consists of a?
protons(+) an neutrons(=) inside the nucleus and electrons(-) revolving around it.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Which 2 parts in an atom have the same mass?
Protons and neutrons have approximately the same mass in an atom. Protons have a mass of about 1 atomic mass unit (amu), while neutrons have a slightly larger mass of about 1 amu.
What has the same mass of a proton?
Neutrons have the same mass as that of a proton. Neutrons and protons are present in the nucleus
The mass of neutrons and electrons are about the same?
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Which other particles have almost the same mass as protons?
Neutrons have almost the same mass as protons. They are both subatomic particles found in the nucleus of an atom and are collectively referred to as nucleons. The mass of a neutron is only slightly greater than that of a proton.
In subatomic particles do protons and neutrons have the same mass?
No, protons and neutrons do not have the same mass. Protons have a slightly smaller mass than neutrons. The difference in mass between the two particles is due to the different composition of quarks that make up each particle.
Which subatomic particles are closest in mass?
Protons and nuetrons Dom says: Protons and 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.
Neutrons and what almost have the same mass?
A neutron and a proton almost have the same mass. A neutron and 1,840 electrons almost have the same mass.
Which isotopes have the same mass?
The number of protons and neutrons is what determines the mass of an isotope. Even though isotopes of a particular element have the same number of protons, but a different number of neutrons, which causes their mass to be different.
What two particales have approximitly the same mass?
Protons and Neutrons
