Concept explainers
(a)
Interpretation:
The element in the same period as that of tellurium but with number of protons three fewer than tellurium needs to be determined.
Concept introduction:
A periodic table expresses the position of elements often organized in seven rows and eighteen columns, the rows are the periods and the columns are the groups. The elements are organized in increasing order of their
The first group is named as alkali metals, the second group is known as alkaline earth metals, the groups from 3 to 12 are called as transition element and the element right to transition element is called post-transition element.
From group 1 to 12, all elements are metals; some metals belong to post
(b)
Interpretation:
The element in group 14 which is a post-transition metal needs to be identified.
Concept introduction:
A periodic table expresses the position of elements often organized in seven rows and eighteen columns, the rows are the periods and also the columns are the groups. The elements are organized in increasing order of their atomic number. Atomic number is the number of protons in an atom.
The first group is named as alkali metals, the second group is known as alkaline earth metals, the groups from 3 to 12 are called as transition element and the element right to transition element is called post transition element.
From group 1 to 12, all elements are metals; some metals belong to post transition elements. The elements like boron, aluminum, silicon, germanium, arsenic, antimony, tellurium, polonium, and astatine are called metalloids. Metalloids are elements with both metallic and non-metallic property. The element right to metalloid is called non- metal.
(c)
Interpretation:
The element which is an alkali with 19 protons needs to be determined.

(d)
Interpretation:
The element which is present in group 15 and it is metalloid with the number of protons more than 40 needs to be determined.
