Why hydride are called so?

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.


What takes place within the atoms of a material when the material becomes negativly charged?

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.


Is an anion an ion with more electrons than protons giving it a negative charge?

Yes, an anion is an ion with more electrons than protons giving it a negative charge.


When an atom has more electrons that protons it is?

An anion is an ion with more electrons than protons.


Why do the properties of an anion differ from those of its parent atom?

The anion has a negative electrical charge and is more chemically reactive than the atom.


What is the atom with the most electrons than protons is called?

If you mean an atom with more electrons than protons it is called an ion. More specifically an anion (negatively charged)


Is boron a cation or an anion?

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.


What element contains more than one element and has metallic properties?

No element contains more than one element.


What is an atom that has more electrons than normal referred to as?

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.
