What is the name of the group I elements?
alkali metals
The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
What are the elements in Group 1 and 2 called?
For example, the elements of Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.
What are groups known as on the periodic table?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered. Groups may also be identified using their topmost element, or have a specific name.
What are elements in group 2 called?
Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What are the following groups known as Group 1?
Group 1 is known as the alkali metals.
What is the other name for the Group 1 elements Why are they called so?
Group 1 elements are called alkali metals because their oxides are soluble in water and group 2 elements are called alkaline earth metals as their oxides form in the earth and are water soluble.
What is the common name given to the element of group 1 Why?
Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.
Which of the following is also known as group of commands?
Answer: Command group: This group is also known as task group. A task is defined as cross-functional activities, carried out by group members to accomplish a common goal. A team represents the nature of a command group.
What are the following groups known as Group 18?
Noble gases – The elements of group 18: He, Ne, Ar, Kr, Xe, Rn.
How many elements are there in Group 1 on the periodic table?
There are six elements in group 1 of the periodic table and they are: Lithium; Sodium; Potassium; Rubidium; Caesium; Francium; You can see them in the first column of the periodic table – below: All these elements have just one electron in the very outside layer of the electrons that surround the nucleus. The elements in group 1 are often called the alkali metals.
What characteristics does Group 1 on the periodic table share?
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. The alkali metals share similar physical and chemical properties. The alkali metals also have low densities.
What families are in Group One periodic table?
Group 1: alkali metals,or lithium family
What do the groups tell you on the periodic table?
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Elements in a group share a common number of valence electrons.
