Chemical Composition Of The Body

Front 1

ACID

Back 1

1. MOLECULE THAT CAN RELEASE PROTONS(H+).
2. PROTON DONOR

Front 2

HYDROGEN BONDS

Back 2

1. HYDOGEN FORMS A POLAR BOND WITH ANOTHER ATOM.
2. HYDROGEN HAS A SLIGHT POSITIVE CHARGE.
3. WEAK ATTRACTION FOR A SECOND ELECTRONEGATIVE ATOM.

Front 3

ATOMS

Back 3

1. SMALLEST UNIT OF MATTER THAT CAN UNDERGO A CHEMICAL CHANGE.
2. NUCLEUS (CENTER) CONTAINS PPROTONS(+ CHARGE) AND NEUTRONS(NO CHARGE).

Front 4

HYDRPHOBIC

Back 4

1.CANNOT FORM HYDRATION SPHERES.
2. NONPOLAR COVALENT BONDS.

Front 5

VALENCE ELECTRONS

Back 5

1. ELECTRONS IN THE OUTERMOST ORBITAL THAT PARTICIPATE IN CHEMICAL REACTION(IF THE ORBIT IS NOT COMPLETE.
2. FORM CHEMICAL BONDS.

Front 6

ELECTRONS

Back 6

1. OUTSIDE NUCLEUS
2. NEGATIVE CHARGE.
3. ORBIT NUCLEUS.

Front 7

CHEMICAL BONDS

Back 7

1. INTERACTION BETWEEN VALENCE ELECTRONS BETWEEN 2 OR MORE ATOMS.
2. NUMBER OF BONDS DETERMINED BY NUMBER OF ELECTRONS NEEDED TO COMPLETE OUTER ORBITAL.

Front 8

IONIC BONDS

Back 8

1.ONE OR MORE VALENCE ELECTRONS FROM AN ATOM IS COMPLETLY TRANSFERRED TO A SECOND ATOM.
2. FIRST ATOM LOSSES AN ELECTRON AND BECOMES A POSITIVELY CHARGED ATOM(CATION BECAUSE IT HAS MORE PROTONS THAN ELECTRONS).
3. THE SECOND ATOM WILL GAIN AN ELECTRON & BECOME A NEGATIVELY CHARGED ATOM(ANION).
4. CATION & ANION ATTRACT & FORM IONIC COMPOUND.
5. WEAKER THAN POLAR BONDS.
6. DISSOCIATE EASILY WHEN DISSOLVED IN WATER.

EX: NACL------NA+ CL-

Front 9

COVALENT NONPOLAR BONDS

Back 9

1. ATOMS SHARE VALENCE ELECTRONS.
2. ELECTRONS ARE EQUALLY DISTRIBUTED BETWEEN 2 IDENTICAL ATOMS.
3. STRONGEST BOND.

EX: H2

Front 10

HYDOPHYLLIC

Back 10

1. FORMATION OF HYDRATION SPHERES.
2. POLAR COVALENT BONDS.

Front 11

COVALENT POLAR BOND

Back 11

1. ELECTRONS ARE SHARED BETWEEN TWO DIFFERENT ATOMS.
2.ELECTRONS MAY BE PULLED TOWARDS MORE ATOMS.

EX: OXYGEN,NITROGEN & PHOSPHATE PULL ATOMS TOWARD THEMSELVES.

Front 12

ATOMIC MASS

Back 12

SUM OF PROTONS AND NEUTRONS.

Front 13

HYDROGEN BONDS

Back 13

1. HYDOGEN FORMS A POLAR BOND WITH ANOTHER ATOM.
2. HYDROGEN HAS A SLIGHT POSITIVE CHARGE.
3. WEAK ATTRACTION FOR A SECOND ELECTRONEGATIVE ATOM.
