This is a polyatomic anion.
the number of electrons in the outer shell .. for metals its less than 4 .. for non metals its more than 4 .. for semi its 4
An anion has more electrons than a neutral atom.
An anion IS an ion.
Hydrides contain either anions of the formula H-1 or covalent bonds in which hydrogen is the more electronegative element. "Hydride" is derived from hydrogen in the same pattern as "oxide" is derived from oxygen, by changing the ending of an element name to "ide" for an anion of the element, or by extension for a covalent bond in which the element is more electronegative than the atom to which the element is bonded.
The atom becomes an anion atom, because there are more electrons than a usual atom of a certain element. Because for every electron there is a proton to match it in a regular atom of a certain element. When there are more electrons than protons, the atom becomes negatively charged, or an anion.
Yes, an anion is an ion with more electrons than protons giving it a negative charge.
An anion is an ion with more electrons than protons.
The anion has a negative electrical charge and is more chemically reactive than the atom.
If you mean an atom with more electrons than protons it is called an ion. More specifically an anion (negatively charged)
Boron is a metalloid element with the symbol B. In chemical compounds, boron tends to form covalent bonds rather than ionic bonds, so it does not typically exist as a cation or anion in its pure elemental form.
No element contains more than one element.
An atom with extra (a higher number than that of its protons) electrons is an anion. An atom with a lower count than its protons is a cation. They are often reffered to as positive (cation) or negative (anion) Ions. An Ion is defined as a charged particle.
