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.
yes the mass of an electron is much tinnier fraction of the mass of an atom
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
What relationship exists between the electron structure of Group IA ion and the electron structure of the nearest Noble Gas?
The atomic number, proton and electron are all the same amount in an element.
in the third shell, an electron has more energy and is further from the nucleus
black
They have opposite charges.
The proton mass is about 2,000 times greater than the electron mass.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
The proton mass is about 2,000 times greater than the electron mass.
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
Planets.
mass of electron = 1/1836 mass of proton (or neutron)
Mass ratio proton (neutron)/electron: 1 836
The valance electron configuration is the same in each at ns1 where n = the period number.
