The mass of a proton is about 1.67 * 10−27 kg or 1.007 atomic mass units.
Neutrons are very close to this, at 1.675 *10-27 kg, or 1.009 Atomic Mass units.
Electrons have a mass less than approximately 1/1836 of this so can effectively be ignored.
What else can I help you with?
What is the smallest atom?
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
What is the name of the part of the atom that has a negative charge?
The part of the atom that has a negative charge is the electron. Electrons are located in the electron cloud surrounding the nucleus of an atom and contribute to the atom's overall negative charge.
When figuring atomic mass the mass of is ignored?
When calculating atomic mass, the mass of electrons is typically ignored because it is so small compared to the mass of protons and neutrons. Electrons have a much smaller mass relative to protons and neutrons, so they do not significantly contribute to the total atomic mass of an atom.
What happens when an electron is added to an atom it will acquire?
when an electron is added to an atom, the atom will acquire a negative charge.
What kind of atom tends to have one electron?
The hydrogen atom has 1 electron.
What particle of an atom has very little weight?
electron
What is the smallest atom?
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
Where is the most of an atom found?
The nucleus has most of the mass (weight) of an atom. The size of the atom, however, is related to its electron cloud (i.e. to the electrons that orbit around the nucleus)
How do elements of the periodic table interact?
Listed in order of atmoic weight. Electrons have the majority of weight in the atom (proton, neutron, electron.)
Is the electron cloud heavy?
No, the electron cloud is not heavy. An electron weighs approximately 2000 times less than a proton or a neutron, so almost all the weight of an atom lies in the nucleus, not in the electron cloud.
Why do electrons not count when you talk about the mass of the atom?
atomic mass means he weight of atom so electron is lighter than proton and neutron thats why it not count in mass of atom
How Atoms can accept or lose electron's. If an atom loses an electron what will its resulting charge be?
Gain of an electron transform the atom in an anion.Loss of an electron transform the atom in a cation.
How are your results similar to the distribution of electron of an atom?
The results of an atom's electron distribution are similar to our calculations in that both involve the probability of finding a particular entity (electron or result) in a specific state. Just as the electron cloud represents the likelihood of finding an electron in a particular location, our results show the likelihood of obtaining a specific outcome in our experiment. Both concepts involve probability distributions to describe possible states or outcomes.
Is an electron in a hydrogen atom the same as an electron in a uranium atom?
yes
What happpens when an atom has lost an electron contact with an atom that has gained an electron?
It forms a new atom.
What is the method to calculate the radius of a niobium atom?
The radius of a niobium atom can be calculated using the formula for atomic radius, which is the distance from the nucleus to the outermost electron shell. This can be determined experimentally through techniques such as X-ray crystallography or theoretical calculations based on the element's atomic number and electron configuration.
If the electron in a hydrogen atom were the size and weight of a golf ball what would be the size and weight of the proton and neutron and what would be the orbital diameters of the electron and neutr?
If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).
