Answer:
(Question) If only an element’s atomic number and weight are provided, what other atomic information can be determined for a neutral atom?
(Answer) the number of protons, electrons and neutrons
(Question) What quality differentiates hydrogen (H) from the other elements in group 1, the alkali metals?
(Answer) It is a non-metal.
(Question) On which atomic property proposed by Henry Moseley is the current periodic table of the elements based?
(Answer) atomic number
(Question) You plan to pass alpha particles through a field that contains a consistent type of particle. Which configuration will result in the largest deflection of alpha particles?
(Answer) low-energy alpha particles passing through a field of high mass-number-particles
(Question) Which statement about metals and nonmetals is correct?
(Answer) Metals can be hammered into thin sheets, and nonmetals are brittle.
(Question) Based on properties of elements in the periodic table, which element is the best conductor of thermal energy?
(Answer) vanadium (V)
(Question) Which element has four valence electrons?
(Answer) silicon (Si)
(Question) Which statement best explains why hydrogen’s atomic number is equal to its mass?
(Answer) Hydrogen does not have any neutrons.
(Question) Which statement correctly compares the valence electrons for atoms of francium (Fr) and barium (Ba)?
(Answer) Francium has fewer valence electrons, but they are in a higher energy level.
(Question) Why are the noble gases the least reactive elements?
(Answer) They have a full valence electron shell.
(Question) Group 2 elements have two valence electrons. Which kind of bond will they most likely form, and why?
(Answer) An ionic bond is likely because they will want to give away two valence electrons in order to become stable.
(Question) How many electrons can carbon accept from other atoms while bonding?
(Answer) four
