What else can I help you with?
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 two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
What has approx the same mass as a neutron?
A protons mass is about 1.001 times the mass of a neutron, so their masses are fairly close.
How do you determine an atom's mass number?
mass number= no. of protons + no. of neutron
Why are some isotopes weighted more heavily than others?
The type of element is decided by the number of protons in it's nucleus. Number of neutrons are either equal or more than number of protons. Mass of proton and neutron is almost equal and that of electron is almost negligible as compared to both of others. As number of neutrons differ, mass of the elements also differ. Though they have 'same' chemical properties. Such atoms with different mass are called Isotopes. If the number of neutron is more, then such Isotopes are having more mass (or weight.)
What has mass in atom?
i think it's Neutron and protons
What is the mass of a proton is approximately equal to the mass of?
The mass of 12 protons is approximately equal to 12 atomic mass units.
Which has the least mass protons neutrons or electrons?
This particle is the neutron.
How many protons and nuetrons?
hey perhaps your question is incomplete. but if your question is what is protons and neutron relationship then a neutron plus a positive charge having mass equal to electron mass then proton forms.
How does an electron differ from neutron?
Neutrons are neutral sub atomic particles found in the nucleus of an atom (along with positively charged protons). Electrons are negatively charged sub atomic particles that are revolving around the nucleus of an atom. The mass of neutron is 1 amu and the mass of electron is about 1837 times less than that of neutron.
How do you find the neutron of the elements?
Atomic Mass of element - the number the protons.
How does the mass of the neutron compare with the mass of the proton?
The mass of a neutron is slightly greater than the mass of a proton. The neutron has no electric charge while the proton has a positive charge (+1 elementary charge). The mass of a neutron and a proton are 1.67492729(28)×10−27 kilograms and 1.672621637(83)×10−27 kilograms respectively. That makes the neutron about 25/10,000ths more massive than the proton.
