The nature of Bonds Flashcards
What is ionic bonding found between
non-metal + metal
What is covalent bonding found between
non metal + non-metal
What is metallic bonding found between
metal + metal
why are metals conductive?
due to the sea of delocalised electrons
what is the point of chemical bonding
chemical bonding occurs for atoms to get a stable electron configuration
define a chemical bond
a chemical bond is an electrostatic force of attraction between elements with a positive and negative charge
giant covalent
high melting point
simple covalent
low melting point (small molecules)
what is ionic bonding
an electrostatic attraction between oppositley charged ions
how to drawn ionic bonding
dot and cross diagram
how to draw covalent bonding
dot and cross diagram but with overlapping orbital
Why is a covalent bond formed
By sharing a pair of electrons (each electron donates an electron each to the shared pair)
