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 ( 

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

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).

Elements of group-1 are called alkali metals and those of group-2 are called alkaline earth metals. Group-1 elements are called alkali metals as these metals form oxides and hydroxides which combine with water to form alkali. Alkali word is derived from the Arabic word ‘alquis’ meaning plant ashes which are rich in the carbonates of sodium

Group 1 contains elements placed in a vertical column on the far left of the periodic table. The elements in group 1 are called the alkali metals. Group 1 is on the left-hand side of the

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

What are the Group 1 elements called? Francium(Fr). All these six elements are called alkali metals. These elements are placed in the vertical column on the 

Group 1 metals are a lot MORE REACTIVE than transition metals- they react more vigorously with water, oxygen or group 7 elements. Group 1 metals are also a lot LESS DENSE, STRONG and HARD than the transition metals, and have much LOWER MELTING POINTS.

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

Mar 29,  · Best Answer. Copy. Hydrogen with atomic number 1 is placed in group1 and period 1 in the modern Periodic Table. Wiki User. ∙ -03-29 15:46:23. Study guides.

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.

One of the largest and fastest growing companies in the testing sector, Element's laboratories span the US, UK, Netherlands, Belgium, Germany, Spain & Asia.

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 

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.

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon. In the periodic table of the elements, it is expected to
