Metals & Non-Metals Metals: Good conductors of heat and electricity. Have shining luster. Malleable (this means that they can be hammered or distorted). Ductile (this means that they can be drawn into wires). Most have high melting and boiling points. Are sonorous (give out sound when beaten). Usually solid at room temperature. An exception to this is mercury‚ which is liquid in nature. Examples: Aluminum‚ Gold‚ Copper‚ Silver‚ Sodium‚ Potassium‚ Mercury. Corrode or oxidize in

stronger forces. DENSITY Because mass increases faster than volume. REACTIVITY OF GROUP 1 The number of occupied shells increases. The atomic size increases. The valence gets further away from the nucleus. The strength of attraction from the nucleus to the valence electron gets weaker. The valence electron is loosely held and it is easy for the elctron to be released to form stable octet lectron arrangement. The reactivity of G1 is the tendency of the atom to release elctron to form stable electron

The purpose of the lab “All in the Family” was to compare the reactivity of the halogens Chlorine‚ Bromine‚ and iodine by observing the reactions between their elemental forms and their ionic forms. To accomplish this experiment‚ we first added a squirt of pet ether to two test tubes. Then‚ we added the same amount of Cl2 to both of the tubes‚ shook the mixtures‚ and recorded the color that resided in each mixture as the initial color. After‚ a squirt of NaBr was added to one test tube‚ and a squirt

1.5.1 Comparison of Three Isomers of Butanol Introduction: An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol);

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed
