Test guide in Chemistry (Ionic and Covalent Naming)

Write your name: Reminders for Students Common Mistakes: Choose the correct word in the paragraph below. Click the box to choose the answer. There are two types of compounds. These are ionic and covalent. Ionic compounds are the bonding between metals and non-metals while covalent compounds are the bonding between non-metals and non-metals. Ionic compounds involve the transfer of electron while covalent compounds involve the sharing of electrons. In ionic compounds, when metal gives up the electron and non-metals accept the electron, the metal will become positively charged (also known as a cation) and the non-metal will become negatively charge (also known as an anion). The attraction on the bonding of the ionic compounds is caused by the electrostatic force of attraction. 1.
