If someone picks up an excess of electrons while walking across a carpet their charge would be?
negative protons are positively charged neutrons are neutral electrons are negative the masses of neutrons and protons are approximately equal and electrons, which "orbit" around the nucleus (the protons and neutrons) are much smaller mass-wise protons and electrons charges are equal and opposite
Is a calcium atom larger than a barrium atom?
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
What is the same between neutrons and electrons?
When the number of electrons and neutrons are the same, it means that the number of protons will also be the same amount. For example a nitrogen atom has 7 electrons and 7 neutrons, this means that the number of protons will also be 7.

Why do electrons orbit protons and neutrons?
Electrons orbit protons and neutrons because they are a much lighter particle (a proton weighs more than 2000 times as much as an electron) and because the negatively charged electron is attracted to the positively charged proton, and the attraction holds it on orbit (much as the gravitational attraction of the sun holds the planets in orbit). This arrangement works even without neutrons (as in a hydrogen atom) but the neutrons help to hold a nucleus together when there is more than one proton (and all protons electrostatically repel other protons).
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
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.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
If someone picks up an excess of electrons while walking across a carpet their charge would be?
negative protons are positively charged neutrons are neutral electrons are negative the masses of neutrons and protons are approximately equal and electrons, which "orbit" around the nucleus (the protons and neutrons) are much smaller mass-wise protons and electrons charges are equal and opposite
What two particles are in the nucleus?
(The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.) WIkipedia
How does protons nuetrons and electrons differ?
All have spin one-half. Protons have a charge of positive one; electrons, negative one; neutrons, neutral. Protons and neutrons have about the same mass; electrons are much less massive. Protons and neutrons have an internal structure -- ie, they are composed of quarks -- while electrons are just themselves. The first two are "hadrons" and the latter is a "lepton."
How much neutrons and electrons are in plutonium?
All the isotopes of plutonium has 94 protons and 94 electrons. For the number of neutrons of a specified isotope: number of neutrons = rounded atomic mass of the isotope - atomic number (or protons number) For plutonium-239: 94 protons, 94 electrons, 145 neutrons. The atomic number of plutonium is 94.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The neutrons and protons are in the nucleus which determines the element/isotope. The electrons however define the net charge (ie. positive if there are less electrons then protons and negative if more) and it can be changed more easily, than changing the amount of neutrons . Another reason is that electrons have a tiny mass compared to the protons and neutrons and it wouldn't change the mass number by all that much.
What is the net charge of iron with 26 protons 30 neutrons and 23 electrons?
Atomic Number: This is the number of protons an element has. Answer: 26 Atomic Mass: Ignoring electrons, which are incredibly small and don't have much of an effect on the mass... This is the number of protons plus the number of neutrons Answer: 56 (26 protons + 30 neutrons) Net Charge: Protons are positive and electrons are negative. The net charge can be found by subtracting the number of electrons from the number of protons. 0 is neutral. Answer: +3 (26 protons - 23 electrons)
How much neutrons and protons and electrons in a atom?
These numbers actually vary between atom to atom.
Why are protons neutrons electrons called subatomic particles?
Because they are much smaller than an atom
How much protons neutrons and electrons does manganese have?
25 protons 25 electrons normally 30 neutrons but it can vary between 21 and 40.
