The three elements liquid and three elements gases at room temperature should be identified. Concept Introduction: Periodic table is arrangement of different elements with the help of columns and rows in order to characterize elements with similar properties in same groups such as alkali metals, alkaline earth metals, halides, noble gases, transition elements etc. In the periodic table, columns represent groups and rows represents periods. Element: An element is a simplest type of a pure substance which is composed of only one type of matter. For examples; silver, gold platinum etc. Metal: Metals are hard, shiny, malleable, fusible, and ductile. They are good conductor of heat and electricity. They are located to the left of the periodic table. Metalloid: Metalloids have properties of both metals and non-metals. They are in the middle of the periodic table. Non-metal: A non-metal has no lustre, with poor electrical and thermal conductivity. They are in right side of the periodic table. Valence electron: The electrons which are present in the outer most energy level is known as valence electron. Number of valence electrons can be calculated by the group number of the element. Generally, the group number is same as the valance electrons of any elements.

Solution Summary: The author explains that periodic tables are arrangement of different elements with the help of columns and rows. Metals are hard, shiny, malleable, fusible, and ductile.
Definition Definition Elements containing partially filled d-subshell in their ground state configuration. Elements in the d-block of the periodic table receive the last or valence electron in the d-orbital. The groups from IIIB to VIIIB and IB to IIB comprise the d-block elements.

Interpretation Introduction
Interpretation:
The three elements liquid and three elements gases at room temperature should be identified.
Concept Introduction:
Periodic table is arrangement of different elements with the help of columns and rows in order to characterize elements with similar properties in same groups such as alkali metals, alkaline earth metals, halides, noble gases, transition elements etc. In the periodic table, columns represent groups and rows represents periods.
Element:
An element is a simplest type of a pure substance which is composed of only one type of matter. For examples; silver, gold platinum etc.
Metal:
Metals are hard, shiny, malleable, fusible, and ductile. They are good conductor of heat and electricity. They are located to the left of the periodic table.
Metalloid:
Metalloids have properties of both metals and non-metals. They are in the middle of the periodic table.
Non-metal:
A non-metal has no lustre, with poor electrical and thermal conductivity. They are in right side of the periodic table.
Valence electron: The electrons which are present in the outer most energy level is known as valence electron. Number of valence electrons can be calculated by the group number of the element. Generally, the group number is same as the valance electrons of any elements.
