bond is the force of attraction that holds two atoms together as a result of the rearrangement of electrons between them. When atoms bond, a chemical reaction occurs and new substances form. The periodic table reveals the underlying atomic structure of atoms, including the arrangement of the electrons. If you know the number of valence electrons that atoms of different elements have, you have a clue to Key Concepts: Terms in this set (19). How many protons does a nitrogen atom have? The attractive force tat holds two atoms together is called a(n)? chemical bond. Because it can either lose or share electrons when it combines with other elements, each -has some of the properties of metals and...

strong covalent bonds between carbon atoms. an irregular, three-dimensional crystal structure. delocalized, highly mobile bonding electrons. extensive van der Waals forces between carbon atoms. Answer Correct Response: A. This question requires the examinee to relate the properties of substances to their atomic bonds. In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. In that same year Englishman Cockroft and the Irishman Walton first split an atom by bombarding lithium in a particle accelerator, changing it to two helium nuclei.

- Brad pitt moviesAnions are larger than their parent atoms (due to increased electron repulsions), while cations are smaller than their parent atoms (due to a reduction in the number of occupied electron shells). Atomic radius decreases across a period in the periodic table. Atom/ion size increases as the number of occupied electron shells increases.
