What is the name of Group 2 in the periodic table?
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 is Group 3 called in the periodic table?
Transition Metals
The elements from Group 3 to 12 are called Transition Metals. They include the Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, and Zinc families of elements. Transition Metals are hard and dense, are good conductors of heat and electricity, and can be bent easily.
How many valence electrons does group 1 have?
1 valence electron
Group 1 has 1 valence electron. Group 2 has 2 valence electrons. Group 13 has 3 valence electrons. Group 14 has 4 valence electrons.
Why are the elements of Group 1 called alkali metals?
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.
What is the name of group 8A?
noble gases
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
What are the two main groups on the periodic table?
In chemistry and atomic physics , the main group is the group of elements whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
What are the three categories of the periodic table?
Classification of the Elements. The next thing in our review is to classify the elements into three groups. These three groups are: metals, nonmetals, and inert gases. Let’s look at where these groups are located on the periodic table and correlate them with the ability to lose and gain electrons.
What are Group 1 elements?
The Group 1 elements other than hydrogen are called the alkali metals. The Group 1 elements are: Hydrogen. Lithium. Sodium. Potassium. Rubidium.
Why are Group 1 elements called alkali metals?
The Group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution.
