IPC practice test questions
Border - ANS-Metalloids _______ the zigzag line.
Demitri Mendeleev - ANS-Made the first periodic table. He was writing a textbook and wanted to
organize the 63 factors recognized at that time. He based totally his employer just like the
cardboard sport of solitaire.
Fluorine - ANS-The maximum energetic nonmetal.
Group 1A - ANS-Has the maximum energetic metals.
Group 1A - ANS-The Alkali Metal Family. Have one valence electron and are very reactive.
They are not found besides within the shape of compounds in nature.
Group 2A - ANS-The Alkaline Earth Metal Family. Have two valence electrons. Are harder than
Group 1A. Melting factor is better. Differences in reactivity are amongst alkaline earth metals are
proven with the aid of the approaches 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 the planet might not
exist without carbon. Most compounds in your body include carbon. Acquainted with carbon in
the shape of coal or a diamond.
Group 5A - ANS-The Nitrogen Family. Have 5 valence electrons. 80% nitrogen is located in the
air.
Group 6A - ANS-The Oxygen Family. Oxygen is the maximum ample element in the earths
crust. It's miles necessary for existence. The air we breath is 20% oxygen.
Group 7A - ANS-The Halogen Family. Have seven valence electrons. The halogens are notably
reactive nonmetals that react effortlessly with metals.
Group 8A - ANS-The Noble Gases. Helium has two valence electrons. The rest have 8 (or an
octet). All noble gasses are used in neon lighting.
Groups / households - ANS-Each vertical column. Have comparable chemical residences and
comparable electron configurations.
Increasing mass - ANS-Mendeleev prepared his periodic table in horizontal rows in order of...
