Want this question answered?
Proton mass = approx. 1,850 x electron mass.If volumes are similar, then proton density = approx. 1,850 x electron density.
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.
Copper has relatively easily available electron as compare to the iron because copper has bigger atomic size than iron which means the shielding effect in copper is more than iron so the electron of copper can conduct heat more easily and efficiently as compare to the electron of the iron which make iron not a good conductor of heat if it is compair to copper.
What relationship exists between the electron structure of Group IA ion and the electron structure of the nearest Noble Gas?
in the third shell, an electron has more energy and is further from the nucleus
black
They have opposite charges.
Mass ratio proton (neutron)/electron: 1 836
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
Mass ratio proton (neutron)/electron: 1 836
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.
