C2 Flashcards
What is an ionic bond?
A bond between A METAL AND A NON METAL
What is a covalent bond?
A bond between A NON METAL AND A NON METAL
What is a metallic bond?
A bond between TWO METALS
What are the boiling and melting points as well as the conductivity like for ionic bonds?
High melting and boiling points
Only conductive when they are liquid/ molten
What are the melting and boiling points as well as the conductivity like for covalent bonds?
High melting and boiling points and aren’t conductive
What is the melting and boiling point like as well as the conductivity of metallic bonds?
High melting and boiling points and are conductive to
What are the structure and properties of graphite?
Structure= form of carbon in which the atoms form layers that can slide over each other so graphite is much softer than diamond
Properties= Conducts electricity, is soft, high melting and boiling points, slippery
What are the structure and properties of diamond?
Structure= Form of carbon where each carbon atom is joined to 4 other carbons
Properties= hard, cannot conduct electricity, high melting and boiling points
What are the structure and properties of diamond?
Structure= Form of carbon where each carbon atom is joined to 4 other carbons
Properties= hard, cannot conduct electricity, high melting and boiling points
What are the uses of nano particles (name at least 4)
1.) Bendy phones
2.) Sunscreen
3.) Repels water- self cleaning glass?
4.) New structures
5.) Filters
6.) Catalysts
7.) Healthcare
8.) Electronics
What do acids and metals make when they react?
Acid + metals —> salt + hydrogen
What are intermolecular forces?
Attraction between the individual molecules in a covalently bonded substances
What is a polymer?
A substance made from very large molecules made up of many repeating units
What is a polymer?
A substance made from very large molecules made up of many repeating units
What is fullerene?
Form of the element carbon that can exist as large cage-like structures, based on the hexagonal rings of carbon atoms
What is an alloy?
A mixture of two or more elements, at least one of which is a metal
What are the structure and properties of silica?
Structure= similar to diamond
Properties= hard, high melting point, contains silicon and oxygen atoms instead of carbon, and is a semiconductor
