Atoms form bonds with other atoms using the electrons in what energy level? | The outer |
What are four ways that atoms form bonds with other atoms using electrons in their outer energy level? | a.losing electrons(group 1) b. gaining electrons (group 17) c. pooling electrons d. sharing electrons |
To create an ionic bond what do atoms have to do with each other? | They have to gain or lose an electon |
If an atom loses an electron what does it become? | Positive |
If an atom gains an electron what does it become? | Negative |
What are positive or negative atoms? | Ions |
Na+ (sodium) and Cl- (chlorine) are strongly attached to each other, what happens? | An ionic bond is made and table salt is formed |
Are metals' outer energy level electrons held tightly to the individual atoms? | No, they move freely among all the metal ions |
Since the electrons move freely what does this allow? | Malleability Ductility Good Conductivity (outer electrons readily move from atom to atom to transmit current) |
Gaining or losing electrons is difficult so some atoms do what with there electrons? | They share them, this is called Convalent Bonding |
Shared electrons= | Attracted to both atoms nuclei: *Move back and forth between outer energy levels of each atom *Each atom is "stable" some of the time *Form a neutral particle *No ions since electrons aren't lost or gained |
