The charge on a fluoride ion is -1.
It is a single negative charge, so the fluoride ion is denoted F-. The fluorine atom gains one electron to incur a single negative charge of -1.
'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
A fluorine atom can change into a fluorine ion by gaining one electron to achieve a full valence shell. This extra electron gives the fluorine atom a negative charge, transforming it into a fluoride ion.
The formula for magnesium fluoride is: MgF2 magnesium is a +2 charge, fluoride is a -1 so each fluoride gives 1 electron to satisfy its electron shell.
The answer is Ni3+
it gains an atom
When a fluorine atom forms the fluoride ion (F⁻), it gains one electron, resulting in a negative charge. This gives the fluoride ion the same charge as a sodium ion (Na⁺) or other monovalent cations, as both have a charge of ±1. Consequently, fluoride ions can readily bond with cations to form ionic compounds.
It is a single negative charge, so the fluoride ion is denoted F-. The fluorine atom gains one electron to incur a single negative charge of -1.
Fluorine is the name of the element and has 9 electrons. Fluoride is the name of the halide ion, carries a 1- charge and has 10 electrons.
Fluoride is an ion consisting of a single atom of fluorine atom with a -1 charge. The fluoride in toothpaste and other dental products is sodium fluoride , consisting of sodium, and fluorine.
The ion formed by a fluorine atom is called a fluoride ion, which has a charge of -1. It is formed when a fluorine atom gains an electron to achieve a full outer electron shell.
'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
Fluorine forms a 1- ion because it has 7 electrons in its outer shell, this is not very stable. What is stable is a full outer shell of 8 electrons. So a fluorine atom will take an electron (which carries a 1- charge) from another atom to complete this so-called octet.
A fluorine atom can change into a fluorine ion by gaining one electron to achieve a full valence shell. This extra electron gives the fluorine atom a negative charge, transforming it into a fluoride ion.
The formula for magnesium fluoride is: MgF2 magnesium is a +2 charge, fluoride is a -1 so each fluoride gives 1 electron to satisfy its electron shell.
The answer is Ni3+
Zinc fluoride has a charge of +2 for zinc and -1 for fluoride, so the formula for zinc fluoride is ZnF2.
