IPC practice test questions
Border - ANS-Metalloids _______ the zigzag line.
Demitri Mendeleev - ANS-Made the first periodic table. He become writing a textbook and
wanted to organize the sixty three factors acknowledged at that point. He based his agency
similar to the card sport of solitaire.
Fluorine - ANS-The most energetic nonmetal.
Group 1A - ANS-Has the maximum active metals.
Group 1A - ANS-The Alkali Metal Family. Have one valence electron and are very reactive.
They are not discovered besides within the form of compounds in nature.
Group 2A - ANS-The Alkaline Earth Metal Family. Have two valence electrons. Are harder than
Group 1A. Melting point is better. Variations in reactivity are among alkaline earth metals are
proven by using the ways they react with water.
Group 3A - ANS-The Boron Family. Have three valence electrons.
Group 4A - ANS-The Carbon Family. Have 4 valence electrons. Life on this planet would no
longer exist without carbon. Most compounds in your frame incorporate carbon. Familiar with
carbon within the shape of coal or a diamond.
Group 5A - ANS-The Nitrogen Family. Have five valence electrons. Eighty% nitrogen is
determined within the air.
Group 6A - ANS-The Oxygen Family. Oxygen is the maximum considerable element inside the
earths crust. It's far vital for life. The air we breath is 20% oxygen.
Group 7A - ANS-The Halogen Family. Have seven valence electrons. The halogens are
noticeably reactive nonmetals that react without difficulty with metals.
Group 8A - ANS-The Noble Gases. Helium has valence electrons. The relaxation have eight (or
an octet). All noble gasses are used in neon lighting fixtures.
Groups / families - ANS-Each vertical column. Have similar chemical properties and similar
electron configurations.
Increasing mass - ANS-Mendeleev organized his periodic desk in horizontal rows in order of...
