What is the difference between group A and group B elements?
What is the difference between group A and group B elements?
What is the difference between group A and group B elements?
What is the basic difference between group A and group B elements from the electronic configuration point of view. In group A elements, the added electrons goes to the outermost shell. In group B, the additional electron goes to penultimate shell.
What is A and B In modern periodic table?
In the modern periodic table, ‘A’ and ‘B’ are two elements belonging to first and seventeenth group respectively and both of them belong to the third period.
Why groups are divided into A and B?
Answer: Therefore, they find the same position in the periodic table. All the groups are divided into sub groups A and B except 0 and VIII group in the modern periodic table. Position of metals, non-metals and metalloid, position of hydrogen, position of f-block elements, etc.
What elements are group A?
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.
What does A and B mean in Mendeleev periodic table?
Example: Lithium, rubidium, potassium were present in the first group. -The reason why groups in the Mendeleev periodic table were parted into two subgroups having elements possessing the same physical property and chemical properties and they are given the labels as A and B.
What are group B elements called?
transition metals
Group B elements are called transition metals.
What is a group in a periodic table?
group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts.
How many groups and periods are on the periodic table?
Features of Modern Periodic Table. There are eighteen vertical columns known as groups in the modern periodic table which are arranged from left to right and seven horizontal rows which are known as periods. The elements of this group form salts.
What are the group B elements?
The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
Why did Mendeleev divided into groups A and B?
-The reason why groups in the Mendeleev periodic table were parted into two subgroups having elements possessing the same physical property and chemical properties and they are given the labels as A and B.
