Why are protons neutrons electrons called subatomic particles?
Because they are much smaller than an atom
What is the difference between protons neutrons and electrons can I please have a simple answer?
Protons and neutrons have approximately the same mass, but the proton is electrically charged and the neutron isn't. Electrons have a much much lower mass and an opposite electrical charge to that of the proton. That's about as simple as I can get it. It's by no means the only difference between them.
Differentiate between a proton neutron and electron?
A proton has a positive charge, a neutron has NO charge and an electron has a negative charge. All three are spin 1/2 particles and therefore fermions, however, protons and neutrons are each comprised of three elementary particles called quarks, making them baryons, whereas electrons aren't made out of any quarks, making them leptons. The lack of quarks in electrons mean they don't interact with the strong nuclear force, whereas protons and neutrons do. Additionally, protons and neutrons are much more massive, about 2000 times so, than electrons.
How much neutrons does molybdenum have?
Most molybdenum atoms have 54 neutrons. The atomic number (number of protons) of molybdenum is 42, and its weight (number of protons and neutrons) is around 96. 96 - 42 = 54.
Why must a positively charged body have a deficiency of protons?
It doesn't. A positively charged body is deficient in electrons. In an uncharged object there are equal numbers of positively charged protons and negatively charged electrons. Removing electrons will leave more protons than electrons, so the object will be positively charged. Such an object is said to have a deficiency or electrons rather than a surplus of electrons because it is generally easier to remove electrons than it is to add protons. Electrons occupy the outer shells of an atom and have a much lower mass than protons. The protons, by contrast, are bound together in the dense nucleus.
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.
How much protons neutrons and electrons are in roentgenium?
Roentgenium has 111 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope -111
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
