Main group 1 (1A) of the periodic table is given the name of alkali metals. This is the group that begins with lithium (Li) and sodium (Na).

Group 1 Elements The elements in Group 18 are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Group 1 elements are: also known as alkali metals (see why under chemical properties) shiny when cut, but quickly tarnished upon exposure to air soft and can be cut with a knife

i) The group- 1 elements are lithium, sodium, potassium, rubidium, caesium and francium. (ii) Lithium is the lightest metal. (iii) Lithium shows diagonal relationship with Mg. Sodium is the

Group 1 elements are known as Alkali Metals. It includes Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). This group lies in the s block of the periodic table. They are known as s Block Elements as their last electron lies in the s-orbital. They are shiny, highly reactive metals.

element unique chemistry. Because beryllium's chemistry is so different from the other group 2 elements, the term "alkaline earth" is usually restricted to Mg, Ca, Sr, Ba, Ra.!Mg2+ has a similar charge density to Li+, so the two elements show some similar chemistry (e.g., tendency to form useful organometallic compounds).

The way the elements are arranged in the periodic table may look complicated, but much of it comes down to one simple pattern.

One of the most common reactions with group 1 and 2 elements is the reaction with water. · Another common reaction is the group 1 or 2 reaction with oxygen. · The

Questions. 1. Explain why the alkali metals become more reactive down the group. 2. Record your following observations for lithium, sodium and potassium: Physical properties, Heating in air, Heating in Chlorine, Reaction with water. 3. Write the

Group one element shares common characteristics. they're all soft, silver metals. because of their low ionisation energy. Group 2 elements are low density, 

1. Rubidium obtains its name from the Latin rubius, meaning: 2. There are at least _____ known isotopes of rubidium. 3. Because rubidium is so highly electropositive, it readily gives up its one

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air. The name comes from the fact that when these metals or their oxides are dissolved in water, a basic (alkaline

Group-1 Elements of the Modern Periodic Table consist of Hydrogen (H), Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr). Out of these elements except for hydrogen, the remaining elements are popularly known as the Alkali metals. Index History Properties of Group 1 Elements or Alkali Metals Physical Properties

Group 1 elements include the alkali metals, Li, Na, K, Rb, Cs, Fr. The alkali metals are all soft, shiny and metallic when cut.

Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, 

Elements in Group 1 Group 1 The elements are; Hydrogen, H (non-metal) Lithium, Li Sodium, Na Potassium, K Rubidium, Rb Caesium, Cs Francium, Fr Also known as alkali metals, except for hydrogen. Physical properties These metals are soft. Good conductors of heat and electricity. Chemical properties

Best Answer. Copy. Elements in group 1 have 1 electron in their outer shell. Group 7 electrons have 7 electrons in their outer shell. This means that the group 1 element needs to give its electron

Aug 15,  · All of Group 1 elements —lithium, sodium, potassium, rubidium and cesium react vigorously or even explosively with cold water. In each case, the aqueous metal hydroxide and hydrogen gas are produced, as shown: (1) 2 X ( s) + 2 H 2 O ( l) → 2 X O H ( a q) + H 2 ( g) where X is any Group 1 metal.

Hydrogen; Lithium; Sodium; Potassium; Rubidium; Caesium; Francium. Hydrogen – H – element 1. History: Hydrogen is released 

The elements of group 1 are called alkali metals because their oxides and hydroxides form alkaline solutions on treating with water. Therefore, the solution

10.1 GROUP 1 ELEMENTS: ALKALI. METALS. The alkali metals show regular trends in their physical and chemical properties with the increasing atomic number.

Group 16 elements. Group 16 elements [non-metals] gain 2 electrons and from an ion ²⁻. Group 15 elements. Group 15 elements [non-metals] gain 3 electrons and from an ion N³⁻. Group 14 elements. Group 14 elements would have to either gain or lose 4 electrons. This is not possible so they cannot react by forming ions.
