The formulas and names of the oxides of the second-period elements ( Li to N ) have to be given. The oxides of the second-period elements ( Li to N ) are whether acidic, basic, or amphoteric has to be identified Concept Introduction: According to physical and chemical properties, the elements can be divided into metals, non-metals and metalloids. In a group, the metallic character of an element increases from top to bottom whereas in a period, it decreases from left to right. The classification elements in the periodic table as metals, nonmetals, or metalloids can be given as Metals are elements that usually contain 1-3 outer shell electrons. Metals look shining and lustrous and are malleable and ductile. They are also good conductors of heat and electricity. They have low ionization energy and tend to lose electrons forming cations. They are most likely to form ionic compounds. Nonmetals are elements that usually contain 4-8 outer shell electrons. They cannot conduct heat and electricity and are brittle. Also they have high electron affinities and tend to gain electrons forming anions. They are most likely to form molecular compounds.

Interpretation Introduction
Interpretation:
The formulas and names of the oxides of the second-period elements (Li to N) have to be given. The oxides of the second-period elements (Li to N) are whether acidic, basic, or amphoteric has to be identified
Concept Introduction:
According to physical and chemical properties, the elements can be divided into metals, non-metals and metalloids.
In a group, the metallic character of an element increases from top to bottom whereas in a period, it decreases from left to right.
The classification elements in the periodic table as metals, nonmetals, or metalloids can be given as
Metals are elements that usually contain 1-3 outer shell electrons. Metals look shining and lustrous and are malleable and ductile. They are also good conductors of heat and electricity. They have low ionization energy and tend to lose electrons forming cations. They are most likely to form ionic compounds.
Nonmetals are elements that usually contain 4-8 outer shell electrons. They cannot conduct heat and electricity and are brittle. Also they have high electron affinities and tend to gain electrons forming anions. They are most likely to form molecular compounds.
7.105 A student is given samples of three elements, X, Y, andZ, which could be an alkali metal, a member of Group4A, or a member of Group 5A. She makes the followingobservations: Element X has a metallic luster andconducts electricity. It reacts slowly with hydrochloricacid to produce hydrogen gas. Element Y is a lightyellow solid that does not conduct electricity. Element Zhas a metallic luster and conducts electricity. Whenexposed to air, it slowly forms a white powder.A solution of the white powder in water is basic.What can you conclude about the elements fromthese observations?
