Same element that has a different number of neutrons.
Process of chemical decay
Charges particles with unequal number of protons and electrons
Chemical particles with an odd number of electrons
Bond between a positively charged ion (cation) and a negatively charged ion (anion)
Sharing of an electron between atoms
Polar Covalent bond
Electrons are shared unequally between atoms; Ex. Glucose
Non-polar covalent bond
Electrons are shared equally between atoms; Ex. NaCl
Weak bonds between hydrogen and another hydrogen or other slightly negative atom.
