Covalent Bonding Flashcards
1
Q
What is a dative covalent bond?
A
When an atoms will contribute both of the electrons in a covalent bon. Shown using an arrow.
2
Q
How to draw a Lewis structure?
A
1) Note down the number of valence electrons and the number of bonds.
2) Draw out the structure using lines for bonds.
3) Add lone pairs.
3
Q
What is the octet rule?
A
The tendency of atoms to gain a valence shell with a total of 8 electrons.
4
Q
What is the expanded octet?
A
When an atom has more than 8 electrons because there are spaces in the d orbitals.
5
Q
What is a covalent bond?
A
The electrostatic attraction between two non-metals when sharing electrons.
6
Q
What is a resonance structure?
A
When there is more than one area where a double bond can form.
