It is a metal because it it only has two valence (outer level) electrons. In many cases, elements that belong to the same group (vertical column) on the periodic table form ions with the same charge because they have the same number of valence electrons. Here You Go! D)7. How many valence electrons do the halogens have? The other members belonging to the same family comprise chlorine, fluorine, and iodine. They need one electron to complete their octet. S. The size of an atom generally increases: down a group and from right to left across a period. Now, the halogens have seven valence electrons. Valence Electrons DRAFT. The halogens posses seven valence electrons; Explanation: Valence electrons are the electrons in the outermost orbitals of the atoms, which are the orbitals with the highest main energy level (principal quantum number). What are the products when reacting potassium hydroxide and hydrochloric acid? Subatomic Particles: Atoms are the most fundamental building blocks of all matter, and they have within them smaller subatomic particles. you find them on the second from last column on the right of the periodic table). Answers: 2. continue. Bromine belongs to halogen family. The Halogens (F, Cl, Br, I, At) are found in column 17 or the fifth column of the 'p' block of the periodic table. 8, 2, 3.
