That depends on the reaction, and the gain of electrons is refereed to as reduction.
HF is molecular (aka covalent) because it is a bond between two nonmetals in which electrons are shared. In the HF bond, Fluorine has six valence electrons and shares two electrons with Hydrogen. Hydrogen only has these two electrons because it only has a max of two electrons on its outer valence shell. Fluorine has an electronegativity of 4.0 (the highest on the Periodic Table), which is greater than Hydrogen's 2.2, so therefore Fluorine would be considered slightly negative in the bond, and Hydrogen would be slightly positive.It is not ionic because in an ionic bond, electrons are not shared, they are transferred.
We would logically expect calcium and fluorine to combine, since calcium is strongly metallic (donates electrons) and fluorine is very strongly non-metallic (receives electrons). The actual formula is CaF2.
There are a total of 9 electrons so that would be the element fluorine.
Flourine is in Group XVII, which means that it has seven electrons in its outer shell. This means that it is only capable of forming single bonds.
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
Fluorine has the atomic number of 9. This means it has 9 protons in the nuclei of its atoms. So, a neutral fluorine atom would also have 9 electrons.
Fluorine is the element with atomic weight closest to 19 amu. Fluorine has an atomic number of 9, so an electrically neutral fluorine atom would have 9 electrons.
That depends on the reaction, and the gain of electrons is refereed to as reduction.
Magnesium lose two electrons to form MgF2.
I would use green for the neutrons and blue for the protons. It doesn't really matter as long as you make them different colors.
A fluorine atom that has seven electrons in its outer shell would be neutral. A negatively charged fluoride ion, Fl-, forms when a fluorine atom gains one electron so that it has an octet, or a noble gas configuration of electrons.
Neutral fluorine has an atomic number of 9, meaning it has 9 protons and 9 electrons. Trifluorine, were it to actually exist on its own, would be a molecule comprised of three fluorine atoms. Therefore, trifluorine would have 3 X 9 = 27 electrons per molecule.
An atom of fluorine has the greatest attraction among all atoms for electrons; therefore, no other atom can extract an electron from a fluorine atom, as would be required for the fluorine to have a positive oxidation state.
The element that attracts electrons the most would be Fluorine

Fluorine has 7 valence electrons. In order to become stable, Florine will share 1 electron with another atom to get 8 electron and become stable.
