False dear as covalent bonds are formed by sharing of valance electrons.
Ionic bonds are formed by one atom transferring electrons to another atom to form ions.
Elements consist of neutral atoms or molecules, the electrical neutrality is because the number of positive protons equals the number of surrounding negative electrons in their respective energy levels.
Charged particles called IONS are atoms, or groups of atoms, which have lost or gained electrons to have a overall net electrical positive or negative charge.
The atom losing electrons forms a positive ion (a cation) and is usually a metal.
The overall charge on the ion is positive due to excess positive nuclear charge (protons do NOT change in chemical reactions). The atom gaining electrons forms a negative ion (an anion) and is usually a non–metallic element.
The overall charge on the ion is negative because of the gain, and therefore excess, of negative electrons. Therefore an IONIC BOND IS THE FORCE OF ATTRACTION BETWEEN ADJACENT IONS OF OPPOSITE CHARGE.
Threats to Native Wildlife. Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. ... Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.
