ELEMENTS COMPOUNDS MIXTURES (3) (b) Elements can be divided into two groups, metals and non-metals. The list below gives some properties of elements. • brittle • can be hammered into shape • dull • good conductors of electricity
22.6: The Other Group 16 Elements: S, Se, Te, and Po - …
As in group 15, the reactivity of elements in group 16 decreases from lightest to heaviest. For example, selenium and tellurium react with most elements but not as readily as sulfur does. As expected for nonmetals, sulfur, selenium, and tellurium do not react with water, aqueous acid, or aqueous base, but all dissolve in strongly oxidizing acids such as HNO 3 to form oxoacids such as H 2 SO 4 .

The Alkali Metals (Group 1)
The alkali metals are so reactive that they are never found in nature in elemental form. Although some of their ores are abundant, isolating them from their ores is somewhat difficult. For these reasons, the group 1 elements were unknown until the early 19th century

Group 3 element - Wikipedia
Group 3 is a group of elements in the periodic table.This group, like other d-block groups, should contain four elements, but it is not agreed what elements belong in the group.Scandium (Sc) and yttrium (Y) are always included, but the other two spaces are usually occupied by lanthanum (La) and actinium (Ac), or by lutetium (Lu) and lawrencium (Lr); less frequently, it is considered the group
What Determines the Reactivity of a Metal?
25/3/2020· The reactivity of a metal is determined by how tightly the metal holds onto the electrons in its outermost energy level. These electrons are called valence electrons. Metals usually have fewer valence electrons than nonmetals.

Alkaline Earth Metals | Chemistry for Non-Majors
Group 2 elements are referred to as “ alkaline earth ” metals (tan column below). The name “ alkaline ” comes from the fact that compounds of these elements form basic (pH greater than 7) or alkaline solutions when dissolved in water. If the Group 1
iGCSE CHEMISTRY REVISION HELP - The Periodic Table
Fire extinguishers - Carbon dioxide has a higher density than air It can form a layer around a burning material and starve it of oxygen As carbon dioxide doesn’t burn, the fire is put out The copper is in excess and uses up the oxygen to form copper oxide (CuO). All the oxygen in the air is therefore used up, and so the volume of the air decreases by about 20% (the percentage of oxygen in air).
