(a)
Interpretation:
The element boron is to be classified as a metal, nonmetal, or semimetal.
Concept introduction:
An element is a substance that cannot be broken down into any smaller units. An element can be classified as metal, nonmetal or metalloid. The elements in a modern periodic table are arranged in an increasing order of their
(b)
Interpretation:
The element barium is to be classified as a metal, nonmetal, or semimetal.
Concept introduction:
An element is a substance that cannot be broken down into any smaller units. An element can be classified as metal, nonmetal or metalloid. The elements in a modern periodic table are arranged in an increasing order of their atomic number. In this modern periodic table, the horizontal rows are said to be periods and vertical columns are said to be groups. There are seven periods and eighteen groups in a modern periodic table.
