Hydrogen, Lithium, and Potassium
yes
the group1 elements
Alkali Metals
Group I elements are called alkali metals as they are generally basic in nature
because dinner has more dinner
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
Sodium, Na, is in group 1 on the periodic table. The elements in group1 are the elements in that vertical column, which are Li,Na,K,Rb,Cs,Fr.
Group1 is considered Alpha-Numeric because it has both alphabet characters and numeric characters.
Hydrogen is period 1 and group1 element. It has only one electron.
You would get a linear curve because the oxidation state of elements in group 1 increases by one as you move from one element to the next, due to the loss of one electron in their outermost shell. Thus, the plot of oxidation state against atomic number for group 1 elements would result in a straight line.
The alkali metals.
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
