each substance would fit into their discrete groupings. Chemist use bonding types‚ electrical conductivity‚ melting and boiling point and physical properties to classify substances into four main groups‚ which are: • Metallic substances • Ionic compounds • Covalent molecular and; • Covalent network substances Metallic substances are substances that are made up of one or more metal. They have regular 3D lattice of positively charged ions. Metallic substances are bond together

of Chemical Bonds Bond energy refers to the energy that bonds hold with each other‚ it is tested by how much energy it takes to break the bond‚ whatever it takes to break‚ it takes to create and hold. Ionic Bonding is made between two oppositely charged ions come together to form a bond Ionic Compound is a nonmetal and a metal that bonds. Bond Length is the minimal distance between the two atoms. Covalent Bonding is when atoms “share” electrons in order for both of the outer shells are completed

another non-metal to achieve a complete octet. The gain of negatively charged electrons by a neutral atom produces an anion. 7.2- Ionic Bonds and Ionic Compounds Although they are composed of ions‚ ionic compounds are electrically neutral. Most ionic compounds are crystalline solids at room temperature. Ionic compounds generally have high melting points. Ionic compounds can conduct an electric current when melted or dissolved in water. 7.3-Bonding in Metals The valence electrons of metal

compounds. These categories are ionic‚ molecular and metallic substances. In ionic compounds valence electrons are transferred from one atom to another‚ resulting in formation of ions of opposite charge. Metals will lose electrons to form cations (positively charged) and non-metals can gain electrons to form anions (negatively charged); these oppositely charged ions attract each other and form an ionic compound Because the attraction of the ions is so strong‚ ionic compounds are always solid at room

Chapter 6: Chemical Bonds Section 6.1: Ionic Bonding Chemical bond: the force that holds atoms of elements and ions together to become a stable‚ new substance called a compound. -the number of valence electrons determines if an atom will form a chemical bond. -metals tend to give up electrons to other atoms. -nonmetals tend to take electrons from other atoms. -noble gases will not form a chemical bond because these atoms already have a full outer shell of energy.

Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore
