Chem. Ch. 6 Sec. 2

Chemistry Chapter 6 Section 2

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
