Do neutrons have same mass as electrons?
No, protons and neutrons both have a relative mass of 1. Whereas, electrons have a relative mass of (1x10^-5), which is the equivilent to saying that an electron's mass is about 100,000 times smaller than a proton or neutron.
How big are the parts of the atom compared to the whole atom?
Protons and neutrons have a relative mass of one, electrons have a relative mass of 1/2000
What has 8 neutrons and a atomic mass of 14.0067?
Atoms of carbon-14 isotope has six electrons and eight neutrons, so the relative atomic mass of 14.
How relative atomic mass of an atom can be determined?
By adding the neutrons and the protons together, as the electrons are such a small part of the atom it does not matter.
Describe electrical charges particles of the atom?
Well central nucleus surrounded by a cloud of negatively charge electrons.
Do neutrons have same mass as electrons?
No, protons and neutrons both have a relative mass of 1. Whereas, electrons have a relative mass of (1x10^-5), which is the equivilent to saying that an electron's mass is about 100,000 times smaller than a proton or neutron.
What are the relative charges of each part of the atom?
protons positive electrons negative neutrons neutral
What determines an atoms atomic mass?
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How big are the parts of the atom compared to the whole atom?
Protons and neutrons have a relative mass of one, electrons have a relative mass of 1/2000
How many neutrons are in a calcium ion?
it depends on the isotopes of calcium e.g. Calcium-40 has 20 electrons and 20 neutrons Calcium-44 has 20 electrons and 24 neutrons To find out the number of neutrons for Calcium you take the Isotope number (x) minus away the number of electrons (20) e.g. Calcium-x Calcium-x has 20 electrons and (x-20) neutrons.. OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons
What has 8 neutrons and a atomic mass of 14.0067?
Atoms of carbon-14 isotope has six electrons and eight neutrons, so the relative atomic mass of 14.
Why don't you need to worry about the number of neutrons when calculating the charge of an ion?
Neutrons have a charge of 0. You can add all the zeroes you want without affecting the charge.
The 3 subatomic particles?
The three subatomic particles in an atom are protons, neutrons, and electrons:Protons have a relative mass of 1 and a charge of +1, and they are found in the nucleus of an atom.Neutrons have a relative mass of 1 and no charge, and they are also found in the nucleus of an atom.Electrons have a relative mass of 1/1836 and a charge of -1. They are found in specific orbits around the nucleus and are held in these orbits by the positive charge of the protons in the nucleus.
How relative atomic mass of an atom can be determined?
By adding the neutrons and the protons together, as the electrons are such a small part of the atom it does not matter.
Which subatomic particles have similar masses?
Neutrons and protons have mass 1 (relative to proton, given the value of 1).Electrons have mass 1/1840 (relative to proton, given the value of 1).:)Protons and neutrons have almost the same mass.
How are electrons neutrons and protons different?
Protons have a positive (+) charge.Neutrons have no charge.Electrons have a negative (-) charge.Proton and neutron are roughly the same sizeElectrons are considerably smaller than protons or neutronsProtons and neutrons have a relative atomic mass of 1The mass of electrons is so small it is not included in calculations of an atom's mass.
what element has 21 protons 21 electrons and 24 neutrons?
chromium
