It has a value of about 9.109×10−31 kilograms or about 5.486×10−4 daltons, equivalent to an energy of about 8.187×10−14 joules or about 0.5110 MeV.

Answer. Electrons in 1kg: 1/(9.11 * 10^-31) = 1.10 * 10^30.

Depending on the atomic mass, you can calculate the number of atoms, and by knowing the number of electrons in the various orbits of each atom, you can find out the total number of electrons. If you were asking for 1 kg of electrons and it’s count, then ‘n’= 10/(9.11*10^-31)= approximately 10^31 electrons.

Answer: Given : mass of an electron=9.11 x 10⁻³¹kg =9.11 x 10⁻²⁸g 1kg=1000g Number of electrons present in 1kg will be : =1000/9.11 x 10⁻²⁸ =109.76 x 10 ²⁸ ∴ Number of electrons present in 1kg would be 109. 76x 10²⁸ electrons.

Each water molecule has 10 electrons, so multiply that answer by 10 to get the total number of electrons, 3.34 x 10^27 electrons per kg water.

Therefore, the total charge on 75 kg of electrons is −1.33×1013C.

Answer: The charge qe on a single electron is −1.6×10−19C.

Electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.

A neutron is not made of a proton, electron and an antineutrino. These particles are only its decay products. A neutron is made of 3 quarks, one up quark, and 2 down quarks and many many “intermediate particles” called gluons which carry the interaction between the quarks.

The three main parts of a atom is protons,neutrons,and electrons.

Electrons are the largest particles in an atom.

An electron looks like a particle when it interacts with other objects in certain ways (such as in high-speed collisions). When an electron looks more like a particle it has no shape, according to the Standard Model. Therefore, in the sense of particle-like interactions, an electron has no shape.

An electron is a negatively charged subatomic particle that orbits the nucleus of an atom, which contains a positively charged subatomic particle called a proton and a neutral subatomic particle called a neutron.
