Chapter 6 and p. Chapter 7 Flashcards
What is an ionic bond?
A transfer of electrons from a metal to a nonmetal.
Why do ionic bonds transfer electrons?
To form a stable compound
What is a covalent bond?
The sharing of electrons between two or more nonmetals.
Why do covalent bonds share electrons?
To form a stable compound
What is a metallic bond?
A bond between metals forming a sea of electrons.
What is notable about metallic bonds?
The electrons are free
What must all covalent bonds satisfy?
the Octet Rule
What is the octet rule?
All elements/polyatomic ions are stable with eight valence electrons.
A ______ has a positive charge.
A cation has a positive charge.
A(n) _____ has a negative charge.
A anion has a negative charge.
Compounds made of two elements are what?
binary compounds
How are polyatomic ions bonded?
Covalently.
A polyatomic ion has an _______ charge.
A polyatomic ion has an overall charge.
List the order of the prefix/suffix from least to greatest oxygen.
per–ate
ate
ite
hypo–ite
Where are metals with multiple charges located on the periodic table?
Metals with multiple charges are located in the d, f, and p sections of the periodic table.
What is Zinc’s charge?
+2
What is Silver (Ag)’s charge?
+1
What are the prefixes for for 1-9 for covalent bonds?
1 - Mono 2 - Di 3 - Tri 4 - Tetra 5 - Penta 6 - Hexa 7 - Hepta 8 - Octa 9 - Nona 10 - Deca
Covalent bonds are between what?
Two nonmetals
What are diatomic molecules?
Diatomic molecules are molecules of 2 of the same type of atom.
What are elements that can be diatomic?
H, N, O, and column 7
What are the three types of covalent bonds and how many electrons do they share?
single (2 e-)
double (4 e-)
triple (6 e-)
As the covalent bonds increase (single to triple) what happens?
The bonds become stronger and shorter.
What does a lewis structure represent?
A lewis structure represents valence electrons in the bonds present of the covalent bond.
