Protons and electrons have mass and charge.
Protons and electrons are particles that account for the charge of the mass. Protons have a positive charge, while electrons have a negative charge. The net charge of an object is determined by the balance of these two particles.
To calculate the number of electrons, you need to know the total charge of the system or material in question and the charge of a single electron (approx. -1.6 x 10^-19 coulombs). By dividing the total charge by the charge of a single electron, you can determine the number of electrons. Formula: Total number of electrons = Total charge / Charge of a single electron.
Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
This single atom remain an atom of krypton !
The mass of an electron is much smaller than the mass of a proton. An electron has a charge of -1, while a proton has a charge of +1.
A unipositive or uninegative monoatomic ion.
Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.
Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.
Protons have a positive charge and they have mass. Electrons have a negative charge and have almost no mas (it is about 1/2000th that of a proton).
atomic mass = protons + neutronsprotons = atomic mass - neutrons = 18 - 8 = 10 protons (Neon)In ground state, protons = electrons = no charge-1 charge means gain of 1 e-, so number of electrons = 11 electrons
