What groups of elements does the s-block contian?
Group 1 and group 2 elements are called s-block elements
Why are the elements in groups 1A-8A called the representative elements?
They follow a pattern for valence electrons.
Which two blocks of the periodic table make up the main - group elements?
Main group elements include elements (except hydrogen) in groups 1 and 2 (s-block), and groups 13 to 18 (p-block).
What are the main group elements of the periodic table?
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
Which of the following groups of elements are the main group?
nonmetals, alkali metals, and halogens, among others.To be precise it is elements in IUPAC groups 1,2, and 13 to 18 -- otherwise designated as the "s-block and p-block" elements.
What groups make up the main block elements?
The s and p blocks make up the main-group elements, which are also known as representative elements.
Why are the main-group elements called the representative elements.?
S- and p- electrons fill in a regular repeating manner. Hence, elements in the s- and p-blocks have predictable patterns that represent a wide range of properties. Therefore, the s- and p-block elements are called the main-group, or representative, elements. Non-metals, Alkali, Halogens
What elements are in the s block of the periodic table?
the elements belonging to group 1 and 2 of the periodic table are s-block elements. it includes elements in which the outermost subshell is s and that have 1 or 2 electrons in their outermost shell.
What are representatives elements?
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
What are elements that are very reactive called?
They are in the s block. Metals of the 1st group.
Elements that are very reactive are called?
They are in the s block. Metals of the 1st group.
How many groups or columns are in the periodic table?
Omitting the f-block elements, there are 18 groups in the periodic table. Groups 1 and 2 contain s-block elements. Groups 3-12 contain d-block elements and groups 13-18 are made out of p-block elements. The only exception is helium is named under group 18, being a noble gas.
