What are the atoms subatomic particles?
The proton, neutron and electron are the three subatomic particles. Protons and neutrons are formed from quarks and gluons. The proton and neutron carry a (nearly) identical mass. m_p = 1.673 * 10^-27 kilograms m_n = 1.675 * 10^-27 kilograms while the electron is considerably smaller and much less massive. m_e = 9.110 * 10^-31 kilograms For those unfamiliar with scientific notation, those numbers are: m_p = .000000000000000000000000001673 kg m_n = .000000000000000000000000001675 kg m_e = .000000000000000000000000000000911 kg Protons carry a positive electric charge while electrons carry an equal and opposite negative charge. Neutrons are electrically neutral.
Do electrons have the mass as protons?
Protons are part of the nucleus, so they have less mass than the nucleus (except in the specific case of hydrogen, where the nucleus is a single proton so they have the same mass).Electrons are much less massive than protons. It would take 1836 electrons to equal the mass of one proton.Neutrons are very slightly more massive than protons, by just about the mass of an electron. They're close enough that they're generally treated as having essentially the same mass.
What correctly explains why the actual mass of an atom is less than the calculated mass of its protons neutrons and electrons?
The calculated mass of the nucleus is always greater than the experimentally determined mass.This difference is variously called as mass defect,mass deficit or mass decrement.The reason for mass defect is that,this deficit mass has been transformed into the nuclear binding energy by Einstein equation E=mc2.
Is mass of electron nearly 1840 times less the mass of proton?
Electron is the lightest sub atomic particle it is 1836 times less than as that of the mass of the proton it's mass is 9.1*10-31kg
How does an atom enter into the excited state?
An exited atom radiate through the process to gain stability. When the ratio or protons to neutrons is less or higher than that corresponding to the stability ratio the nucleus radiate either:beta (-) radiation to reduce the number of neutrons, orbeta (+) radiation or electron capture to reduce the number of protonsgamma radiation to bring the nucleus to ground state energy level.Also an excited atom emits radiation (Alpha, beta, gamma, neutrons, ...) when the nucleus atomic number is higher than 83 to reduce the number of nucleons in thenucleus to reach stability.
What particle control the 'weight' of an atom?
The weight of an atom is primarily controlled by the total number of protons and neutrons in its nucleus. Protons and neutrons have approximately the same weight, while electrons have negligible mass compared to protons and neutrons.
What differentiates each subatomic particle?
The mass and the charge. Protons are positively charged. Electrons are negatively charged. Neutrons have no charge. Protons and neutrons have similar mass (about 1 amu). The mass of electron is about 1822 times less than that of protons / neutrons.
Which particles account for almost all the mass of an atom?
Protons and neutrons account for almost all the mass of an atom. Electrons have much less mass compared to protons and neutrons.
What element has 48 neutrons and a mass less than 100?
Cadmium atomic number is 48. so, it can have 48 protons and neutrons and electrons each. it has mass less than 100. 96cadmium has 48 protons and 48 neutrons. 96 means its mass i.e, number of protons and number of neutrons
Why do smaller atoms have less neutrons than protons?
I don't see why not
Which particles determine the mass of an atom?
The atomic mass unit is defined to be 1/12 of the mass of a carbon-12 atom. Atomic masses can determined by weighing molar amount of an isotope. Absolute masses (in kg) are determined by measuring the amount that charged atoms are deflected by magnets, since if you know the charge you can calculate mass from the amount of deflection.
How much of an atom mass does the nucleus make up?
I believe that in gold atoms, 99.994% of the mass comes from its nucleus. Electrons way thousands times less than neutrons and protons, and since the protons/neutrons are nucleons the mass comes from the nucleus.
What Particles responsible for the mass of atom?
The three main sub-atomic particles of an atom are proton, neutron and electron. The mass of a proton is about 1800 times the mass of an electron and the masses of proton and neutron are almost similar. Hence, mass of only proton and neutron is counted towards the mass of an atom.
Lighter elements have more or less number of protons than neutrons?
Lighter elements tend to have neutrons equal to protonms or only a slight excess. Heavier elements have an excess of neutrons over protons
What contributes to the most of the mass of an atom?
The majority of the volume in an atom is filled by the neutrons and the protons. Although the electrons do have a volume, they occupy significantly less space than the other two subatomic particles
How many protons could a stable atom with 90 neutrons potentially have?
A stable atom with 90 neutrons could potentially have a maximum of 90 protons, as the number of protons would have to be equal to or less than the number of neutrons for the atom to be stable.
How many protons and electron does sulfur have?
Sulfur has 16 protons and supposedly also 16 neutrons however there will almost certainly be other isotopes with more or less neutrons
