Covalent and Metallic Bonds

Electrons are BLANKED in a metallic bond

shared

Metalic bond are between what two elements

metals

properties of metallic bonds

good conductors, ductility, malleability

Alloys

metals combining with other metals/ mixture of metals

Substitutional Alloys

metal alloys are approximitally the same size and substitute in for one another

interstitual nalloys

metals with a smaller radius fit between cations

properties of substitutional alloys

looking for conductivity, stretch and pull-but still strong

properties of interstitial

strong, not malleable, used for construction

covenant bond

the sharing of electrons between two nonmetals

naming covalent bonds

step 1- name 1st nonmetal by it element name

step 2-name the second nonmetal by using its element name and replacing second syllable with -ide

step 3- add prefixes to subscripts

Do you ever put mono infront of the first element name 

NO

When using mono in front of second element that begins with O what do you do

drop an o

when using di- and tri- in front of an element that begins with an i do you keep both i’s

YES

If the prefix ends with a and the element starts with o what do you do

drop the a

prefix for 1

mono

prefix for 2

di

prefix for 3

tri-

prefix for 4

tetra

prefix for 5

penta

prefix for 6

hexa

prefix for 7

hepta

prefix for 8 

octa

prefix for 9

nona

prefix for 10

deca

steps to making lewis diagrams 

1. count v.e.

2. determine central atom

3. draw single bonds into second atom

4. put all valence electrons as lone pairs 

5. turn lone pairs into double or triple bonds
