I suspect you mean the pnictogens. Elements in this group include nitrogen, phosphorus, arsenic, antimony and bismuth. Please see the link.
Elements with more than 92 protons are called Transuranic elements.
Because some of the second period elements show a diagonal relationship with the elements of third elements in showing a similar kind of propertiesLi and Mg show diagonal relationship Be and Al also and many more
This would be called an element, or a mono-atomic compound.
The repeating pattern of elements of their properties is called periodicity. Elements are arranged according to same chemical properties.
Vertical columns are called groups. Horizontal rows are called periods.
No, they are not.
They are called ions
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
The representative elements are located in groups 1A through 7A. They are referred to as representative elements because they display a wide range of physical and chemical properties. Some are metals, some are nonmetals, and some are metalloids. The S and P sub-levels of the highest energy are not filled.
some guy called Mendeleev
Sometimes these are called the "representative" elements.
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.
Elements 58 to 71 are called the Lanthanides.
CARBON
They are called f-block elements. The first row elements are called lanthanides. The second row elements are called actinides.
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.
