Fluorine, F, has the atomic number 9. Atomic number is the number of protons, so fluorine atoms have 9 protons in their nuclei. In a neutral atom, the number of protons and electrons are equal. So a neutral F atom will have 9 electrons.
Well if I'm not mistaking, which I might be. It has 55 protons and I'm not positive on electrons but I would guess 55 also
Fluorine ion (F-) has a larger size than a neutral fluorine atom (F) because the additional electron in the F- ion increases the electron-electron repulsion, causing the electron cloud to expand. This results in a larger effective atomic radius for the fluorine ion compared to the neutral fluorine atom.
The electron configuration of fluorine is 1s22s22p5. To form the F- ion (fluoride ion), one electron is gained to achieve a full valence shell. Therefore, the missing number of electrons in the electron configuration of F after gaining one electron is 1.
Cl and F
The electron configuration of fluorine is 1s2 2s2 2p5.
An electron.
A electron cloud, a electron, protron,neutron,and the nucleus
the electron is the smallest in terms of mass. 9.11E-31kg/electron 1.67E-27kg/neutron 1.67E-27kg/proton
Well if I'm not mistaking, which I might be. It has 55 protons and I'm not positive on electrons but I would guess 55 also
A proton has a mass over 1,800 times that of an electron (taken from this already-asked question: http://wiki.answers.com/Q/Is_a_proton_or_electron_heavier)
Electrons don't decay, so you probably mean a neutron emitting an electron and becoming a proton? If so, the new atom would be Oxygen.
Positive.
i need a power cord compatiable to a protron pltv -32

negative.
Yes they are and they are in the nucleus with the neutrons.
