An ionic bond forms when electrons are transferred between atoms.
Calcium is a metal element. There are 20 electrons in a single atom.
Na2O
electrons must be transfered from one atom to another
conductors conduct electricity well because the electrons are easily transfered from atom to atom.
An ions is formed when an atom gains or loses electrons.
Electronegativity
To form ionic bonds, electrons are transferred from one atom to another.
An ionic bond is when one or more electrons are transfered from one atom to another. A covalent bond is when atoms share one or more electrons. The atom Hydrogen would need only 2 electrons but most need 8.
The pair of electrons is shared to form a covalent bond.
Calcium is a metal element. There are 20 electrons in a single atom.
Na2O
usually a new substance is formed, but the substance formed depends on the reagants used molecule
electrons must be transfered from one atom to another
Atom is formed of electrons, protons and neutrons.
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
conductors conduct electricity well because the electrons are easily transfered from atom to atom.
An ionic bond will form. Covalent bond, however, is when the two atoms share electrons when they bond.
