Names And Formulas Of Compounds Flashcards
What are the 2 types of chemical bonds?
1- ionic bond: bonding of a metal to a non metal element
2- Covalent bond: bonding of two or more non metal elements
What is a Ionic bond
The bonding of a metal to and non metal element
What is a covalent bond?
Bonding of two or more non metal elements
What is ionization?
Ionization:
removing or adding electrons to satisfy the octet rule
Loss of electrons will result in what type of charge?
a positive charge
Gain of electrons will result in what type of charge?
A negative charge
What ion does oxygen form?
O2-
What ions do the halogens form?
Halogens form anions which are negatively charged
Why don’t noble gas form ions?
Because noble gases have full valency shell (8 electrons in outermost shell), which makes them chemically stable and therefore has less tendency to loss or gain electrons
An element that has lost a electron is called what?
Cation or a positive ion
Molecular (Covalent) bonding
What is it?
Bond between non metals
Covalent bond: bond form by atoms sharing electrons
What are the 4 types of molecular compounds?
- Monoatomic
- Diatomic
- Polyatomic
- Binary molecular
What is a monoatomic molecular compound?
A molecule made of one atom of one non metal element
Ex. Neon, Ne
What is a diatomic molecular compound?
Molecular made of 2 atoms of the same element
Ex. H2 or F2
What are the 7 diatomics?
N Nitrogen
H Hydrogen
F Fluorine
O Oxygen
Cl Chlorine
Br Bromine
What is a polyatomic molecular compound?
Molecules made of more than 2 atoms of the same element
Ex. P4 or S8
What is a binary molecular compound?
Molecules containing 2 different non metallic elements
Ex. CO2 and CF4
What are the 3 rules when naming binary molecular compounds?
- First non metal then elemental name
- Second non metal then elemental name but change ending to IDE
- Add prefixes to show number of each atom
What are the 10 prefixes used in naming molecular compounds?
1-Mono
2-Di
3-Tri
4- Tetra
5- Penta
6- Hexa
7. Hepta
8. Octa
9. Nona
10. Deca
