Concept explainers
(a)
Interpretation:
The highest melting point should be determined given structures of second row elements.
Concept introduction:
Periods and Rows in periodic table:
- The horizontal rows of the periodic table are called periods.
- Elements in a period are not similar in properties, all of the elements in a period have the same number of atomic orbitals.
- Every atoms in the top row the first period has one orbital for it is electrons. All of the elements in the second row the second period, have two orbital for their electrons it goes down the periodic table like that.
Second row elements in periodic table:
A period second element is one of the chemical elements in the second row (or) period of the periodic table.
The second period contains the elements lithium, beryllium, carbon, nitrogen, oxygen, flurine and neon.
(b)
Interpretation:
The lowest boiling point should be determined given structures of second row elements.
