Compounds Flashcards
How do atoms make those bonds?
Involves atoms giving away, taking or sharing electrons.
What are compounds formed by?
Metal and a non-metal consists of ions.
Explain a covalent bond and molecule compound…
A compound formed from non-metals consists of molecules. Each atom shares an electron with another atom - this is called a CB. Each atom has to make enough CB to fill up its outer shell.
How is a compound formed?
When different elements react, atoms form chemical bonds with other atoms to form compounds.
What is the definition of a compound?
A compound is a substance formed when two or more chemical elements are chemically bonded together. Two types of chemical bonds common in compounds are covalent bonds and ionic bonds. The elements in any compound are always present in fixed ratios.
What is the definition of a molecule?
A group of two or more atoms linked together by sharing electrons in a chemical bond. Molecules are the fundamental components of chemical compounds and are the smallest part of a compound that can participate in a chemical
Explain a ionic compound…
A compound which is formed from a metal and a non-metal consists of ions. The metal atoms lose electrons to form positive ions and the non-metal atoms gain electrons to form negative ions. The opposite charges (positive and negative) of the ions mean that they are strongly attracted to each other called ionic bonding.
