Chapter 8 Ionic Compounds. Formation of Ions ► Which type of elements are the most stable (least willing to undergo change)? ► How many valence electrons.
HIROSHIMA 1945 August 6 th, 1945 ATOMIC THEORY Part 1: Atomic Structure.
Every atom has its own unique atomic mass based on a standard comparison or relative scale e.g. It has been based on hydrogen H = 1 amu and oxygen O.
Valence Electrons are the electrons in the outermost shell of an atom. They are important in telling how the atom will react with certain chemicals. Like.
Chemical Bonding Chapter 6. Chemical Bond Chemical Bond – an attraction between atoms to hold the atoms together.
Composition of Matter Atom= building block of an element Smallest part of matter Protons= + charge Neutrons= 0 charge Electrons= -1 charge.
