Chemical Bonds Flashcards
1
Q
What is ionic bonding?
A
- the transfer of electrons
- The attraction between oppositely charged ions, made in compounds of metals and non-metals
2
Q
What is a covalent bond?
A
When two atoms share electrons, found in most non-metal elements and non-metal compounds
3
Q
What is metallic bonding?
A
The attraction of positively charged ions to negatively charged delocalised electrons, found in metals and alloys
4
Q
What is an alloy?
A
Mixture of metals and other substances
5
Q
When are ions created/
A
When atoms gain or lose electrons
6
Q
Why are group 0 elements unreactive?
A
Because they have a full outer shell
7
Q
What are cautions and anions?
A
Cation - a positively charged ion
Anions - negatively charged ion
8
Q
What is an ionic lattice?
A
Giant structure that is held together by strong electrostatic forces between oppositely charged ions
