AC/DC was formed in December‚ 1973‚ in Australia‚ by guitarist Malcolm Young‚ whom had just left his last band‚ Velvet Underground. He saw first hand all the benefits that came with being a rock star‚ as his older brother‚ George Young‚ reach the big time as a member of the popular 1960s band‚ the Easybeats. He very much wanted to follow in George’s footsteps. Malcolm also could see that his younger brother‚ Angus‚ was a very talented guitar player‚ even if he was only 15 years old‚ and picked him

Mid-YEAR EXAMINATION REVIEW PACKAGE * Everything around us is considered matter. Everything with a mass and a volume is considered matter. * All matter is made of small invisible particles called atoms. * There are 92 different types of atoms in the universe. * Substances that are made up of one type of atom are called pure elements; therefore there are 92 pure elements in the universe. * Substances made up of more than one type of atom are called mixtures. * Mixtures
