The proton contributes more even though there are equal numbers of both electrons and protons. The mass of a proton is one thousand times greater than the mass of an electron. Thus, the proton contributes more.

Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
How many protons neutrons and electrons an atom of titanium have?
Protons: 21 Neutrons: 29 Electrons: Normally 21
How many electrons are in a neutral atom with 12 protons?
Atoms that are neutrally charged will have the same number of protons as electrons, because one proton will cancel out one electron. To achieve a net charge of 0, 12 protons must be countered with 12 electrons.
What are the main ideas in the nuclear theory of the atom?
Atoms consist of a nucleus of protons and neutrons (the vast majority of its mass) surrounded by a cloud of electrons. In neutrally-charged ions the number of electrons equals the number of protons. The mass of an atom is the sum of the neutrons and protons, whereas the atomic number is dictated by the number of protons alone. An atom with a single proton is hydrogen, and all hydrogen atoms possess a single proton in their nucleus. Helium must have two protons, lithium three, and so on. Atoms (essentially indivisible elements) combine to form molecules via sharing electrons. The main three ideas in the nuclear theory of the atom : 1. An atom is electrically neutral, so the number of negative particles (electrons) is equal to the number of positive particles (protons). 2. An atom is almost entirely empty space, but may be occupied by extremely small, negatively-charged particles called electrons. 3. The positive charge of an atom is located in the center of the atom (the nucleus) which also contains nearly all of the mass of the atom.
What is a carbon atom made of?
Carbon atoms are defined as those atoms which have 6 protons in their nucleus. Aside from that I will note that carbon is a very important element. All forms of life that we know of, including ourselves, could not exist without carbon atoms.
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons
What does Bohrs diagram represent?
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
What tells you how many atoms of an element there are?
the atomic mass, which is the mass of its protons and neutrons and electrons together
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.
Why don't he include the electron in atoms mass?
when compared to the mass of protons and neutrons, the mass of the electrons is negligible and hence not included in atomic mass.
If a certain atoms has 6 protons 6 electrons 7 neutrons what will be its mass number?
If you're asking about atomic mass then the answer would be 13. Protons + Neutrons = Atomic Mass
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.
Protons and electrons have this?
Protons and electrons have mass and charge.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Why protons and neutrons are considered while calculating the mass of an atom?
Because atoms are made up solely Protons, Neutrons, and Electrons. Electrons have essentially no mass, so the other two are the only particles that fractor in.
Atomic mass represents the weight of an atoms protons neutrons and electrons however the atomic mass is generally used to refer to just the number of protons and neutrons why?
its not D
Do isotopes have an even amount of protons and electrons?
depends on the atom, Isotopes are mutations of Atoms, with a different mass number. they still have the same amount of protons and electrons as the proper atom.
