In high school chemistry, we learn that Covalent bonds involve the sharing of one or more pairs of electrons between two atoms. We can represent these bonding pair of electrons in a diagram. The electrons are shown to be midway between the two atoms . For a homonuclear bond (two atoms are the same elements), this is approximately […]
Examples of polyatomic ions Generally, polyatomic ions have suffixes that end in “ite” or “ate” if they contain oxygen atoms. chloride hypochlorite chlorite chlorate perchlorate Note: Chloride shown above is not a polyatomic ion, it’s a monoatomic ion consisting of only one atom. Examples of other polyatomic ions: Oxyanions Oxyanions are ions that contain […]
What are polyatomic ions? Ions are formed when neutral atoms gain or lose electrons. Similarly, a polyatomic ion is formed when a neutral molecule gains or loses electrons. A polyatomic ion is a charged group of atoms covalently bonded together. Majority of the polyatomic ions are anions, meaning they are negatively charged. Ammonium is the […]
AP CHEMISTRY TEACHERS – WE HAVE RESOURCES FOR YOUR ENTIRE CLASS TO USE… Identify if a compound is covalent or ionic You will need to know the periodic table You must be able to identify the non-metals, metals, and transition elements in the periodic table You must be able to categorize a compound as ionic […]
Background: How ionic compounds are formed Ionic compounds are formed from the electrostatic attraction of oppositely charged ions. The ions are arranged in such a way that they form a giant crystal lattice of alternating positive and negative ions. An example of an ionic compound is sodium chloride, NaCl, also commonly known as table salt. […]
Covalent compound A covalent compound involves two non-metals forming a chemical structure together. Rules What are the rules for naming covalent compounds? • Covalent compounds involve multiple non-metals • Covalent compounds use prefixes – to indicate the number of atoms of each element in the compound • The element that further left of the periodic […]
