Naming Compounds CHEMISTRY

• The combining of elements to form compounds through a shift in electronic structure is known as bonding
• Covalent molecules consist of atoms connected by covalent chemical bonds.
• Covalent molecules consist of nonmetals. In a pure -----, the atoms have the same electronegativity values.
• Ionic molecules consist of both metals and nonmetals.
• The cation is the first part of the molecule and is the positively charged one.
• The anion is the second part of the molecule and is the negatively charged one.
• ionic molecules have different electronegativity values
• Diatomic molecules consist of only two atoms
• Diatomics may have a single element (homonuclear) or atoms of different elements (heteronuclear)
• Polyatomic molecules consists of more than two atoms
• A macromolecule is a very large molecule, often consisting of subunits.
• An example of macromolecule are proteins and DNA
• A molecule is electrically neutral
• Ion contains different numbers of protons and electrons
• Group 1 in the periodic table is called Alkali Metals
• Group 2 in the periodic table is called Alkaline Earths
• Group 7 in the periodic table is called Halogens
• Group 8 in the periodic table is called the noble gases
