Section Review ; two main types of chemi-cal bonding are ionic and covalent bonding. Ionicbonds are formed when a transfer of electrons takesplace from one atom to another, and covalent bondsare formed when electrons are shared between atom becomes an ion when it gains or loses oneor more and protons are bothcomponents of atoms; however, they have differentcharges and locations within the atom. Electrons arenegatively charged and found outside the nucleus,while protons are positively charged and found insidethe nucleus. Electrons are also much smaller than atoms are joined together by covalentbonds, the structure that results is a of radioactive isotopes that is useful for dat-ing is the constant rate of Review in awater molecule is caused by an uneven distributionof electrons between the oxygen and concentration of H ions determineswhether a solution is acidic or is the effect of water
