What does the atomic number indiacate?
Number of Proton(or Electron) in the Atom
What is the formula for the atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
What no. ef proton and electron in an atom?
Atomic number = Number of protons = Number of electrons
Why number of electron are equal to the number of proton?
because an atom is electrically neutral
Where there is the same number of proton's as electron's the charge on the atom is considered?
neutral

What is the atomic structure of hydrogen?
Hydrogen is an element. Its atomic number is one. It has one proton in the nucleus, and one electron in the first orbital. It has no neutrons.
What is the size order for these scientific particles Proton Neutron Atom Electron Nucleus?
IIRC Atoms (contains Protons/Neutrons and electrons) Nucleus contains Protons and Nuetrons Proton atomic size 1 Nuetron atomic size 1 electron atomic size 1/1836 i.e the proton is 1836 bigger than the electron
How electron is converted into proton?
An electron will not decay into a proton by any means.
How big is a proton compared to a electron?
A proton is bigger than electron
