Chemical Bonding Flashcards
Elements combine to achieve stability
Chemical Bonding
Two Major Bonds
Covalent and Ionic Bonds
Bonds between Metal and Non Metal
Ionic Bonds
Bond between 2 Non Metal
Covalent Bonds
a charged atom/group of atoms
Ion
It is formed by losing electrons and having a positive charge
Cation (Group 123) Metals
It is formed by gaining electrons and has negative charge
Anion (Group 567) NM
attraction between anion and cations
Ionic Bonds
Ionic bonds form 3D patterns called
Crystal Lattice
ions found in intracellular and extra cellular fluids
Electrolytes
Extracellular Electrolytes is
Na , Cl
Intracellular Electrolytes is
K
In Ionic Formula which is written first
Cations
formed when atoms share 1 or more pairs of valence electrons to become stable
Covalent Bond
This bond is more common in living things
Covalent Bonds
3 formula used for Covalent Bonds
Chemical, Electron Dot, Structural
this formula gives the actual number of atoms per element
Chemical Formula
this formula show the valence electrons involved
Electron Dot Formula
This formula show lines that represent the shared electron and how many bonds are formed
Structural Formula
Shapes of Molecules
Tetrahedron, Pyramid, Bent, and Linear
Four pairs of valence electrons around a central atom
Tetrahedron
Shape with three single covalent bonds
Pyramid
Shape with 2 single covalent bons
Bent / Vshaped
Shape between 2 Atoms
Linear
