Group 1 is known as alkali metals. It includes Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Caesium (Cs), and Francium (Fr). Mnemonic for Group 1: LiNa Ki Ruby Cse Friendship hai. Group 2 is known as alkaline earth metals.
Group 1A is the first (leftmost) column in the periodic table. Except for hydrogen, the elements in Group 1A are the alkali metals. They are Lithium (Li), Sodium(Na), Potassium(K), Rubidium(Rb), Cesium(Cs) and Francium(Fr). … Step 4: Check the two rows at the bottom of the periodic table.
alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

S-BLOCK ELEMENT: MNEMONIC FOR THIS GROUP: LiNa ki Ruby Cse Friendship hai. Group 2 includes Beryllium(Be),Magnesium(Mg),Calcium(Ca),Strontium(Sr),Barium(Br),and Radium(Ra). hence known as alkali earth metal.
Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1. … All these characteristics can be attributed to these elements’ large atomic radii and weak metallic bonding.
Alkali metals react with air to form caustic metal oxides. … Alkali metals react with water to produce heat, hydrogen gas, and the corresponding metal hydroxide. The heat produced by this reaction may ignite the hydrogen or the metal itself, resulting in a fire or an explosion.
- highly reactive at standard temperature and pressure.
- readily lose their outermost electron to form cations with a charge of +1.
The Group 1 elements are called the alkali metals. … All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.
The alkali metals are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). The alkali metals react vigorously with water forming soluble hydroxides which are called alkalis. This is the reason why these metals are called alkali metals.

To remember the trend, first arrange the elements in the order in which they are present in the group: B, Al, Ga, In, Tl. Next, switch the places of Ga and Tl – and you get the correct order of the melting point. There are different types of silicates and remembering them is important.
P-Block Elements Group 13 is known as Boron group or the group of Icosagens or Triels. It includes Boron (B), Aluminium (Al), Gallium (Ga), Indium (In), and Thallium (Tl). Mnemonic for Group 13: B A G I T.

The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements.
The halogens are located on the left of the noble gases on the periodic table. Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. … This characteristic makes them more reactive than other non-metal groups.
Alkali metals are highly reactive at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1.
When sodium is added to water, the sodium melts to form a ball that moves around on the surface. It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears.
Lithium, sodium and potassium float on the surface of the water and are less dense than water. As hydrogen gas is formed, the metals travel around the water’s surface and fizz. As the reactions are exothermic, they will all release heat as they react and they will ultimately vanish.
These all react with cold water with increasing vigour to give the metal hydroxide and hydrogen. … You get less precipitate as you go down the Group because more of the hydroxide dissolves in the water. Summary of the trend in reactivity. The Group 2 metals become more reactive towards water as you go down the Group.
The group 1 elements react with oxygen from the air to make metal oxides . At room temperature, oxygen reacts with the surface of the metal. This forms a white oxide, which covers the surface. … The alkali metals burn vigorously when heated and placed in a gas jar of oxygen.
Soft, silvery-white alkali lithium is the lightest metal and the lightest solid element. Highly reactive and flammable, lithium has to be stored in mineral oil. Industrial applications include heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production.
- Found in column 1A of the periodic table.
- Have one electron in their outermost layer of electrons.
- Easily ionized.
- Silvery, soft, and not dense.
- Low melting points.
- Incredibly reactive.
The name comes from the fact that the oxides of these metals produced basic solutions when dissolved in water, and they remained solids at the temperatures available to the ancient alchemists. Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form.
alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
Group III consists of two subgroups: group IIIb and group IIIa. Group IIIa consists of scandium, yttrium, and lanthanium, which is generally considered with the lanthanoids, and actinium, which is classified with the actinoids. Group IIIb, the main group, comprises boron, aluminium, gallium, indium, and thallium.
In the periodic table, the alkali metals are a group or column containing the chemical elements such as lithium (Li), sodium (Na), rubidium (Rb), potassium (K), francium (Fr) and Caesium (Cs).
Answer: Alkali metals are extremely reactive because they have a single electron in the outermost shell. The presence of a single valence electron makes alkali metal very reactive. They lose electron to gain Noble Gas configuration.
Alkali elements are Lithium(Li), Sodium(Na), Potassium (K), Rubidium (Ru), Cesium (Cs) and Francium (Fr) occupying successive periods from first to seven. Francium is a radioactive element with very low half-life.

As Adrian mentions, take notes as you read in the margin. When you get to a logical break point (section), stop, put the paper aside and try to recall what you just read, in your own words, then continue on. Do for the whole 10 pages, and then at the end, try to recall the paper. Then, go a for a run.
