Structure and Bonding Flashcards
Covalent bonding
Sharing electrons
When elements react together what do they from
They form compounds by gaining or losing electrons or by sharing electrons
Metal atoms lose or gain
Lose electrons to form positive ions because they have lost weight so they are happy
Non metals lose or gain
Non metals gain electrons to from negative ions as they have gained weight and are not happy
What’s an ion
Electronically charged atom, a-e-i-o-u remember
How many electrons do group 1 have in their outer shell
1
Symbol for sodium chloride
NaCl
Ionic bonding what is it between
Metal and non metal
Covalent bonding what is it between
Non metal and a non metal
What is ionic bonding
Ionic compounds held together by strong forces between the oppositely charged ions
Compounds
Two or more elements reacting together
What do the ions form in ionic bonding
Giant structure or lattice
What do all ionic commands have
Giant structures
How can we represent atoms and ions involved in forming ionic bonds
Dot and cross diagrams
Charges on on the ions in an ionic compound…
Always cancel each other out
