Concept explainers
(a)
Interpretation:
Whether metal or nonmetal possess the property of dull powder is to be stated.
Concept introduction:
An element is the basic unit of a substance that cannot be broken down into smaller units. An element can be classified as metal, nonmetal, or metalloid. A metalloid has the properties that are intermediate between metals and nonmetals. A metal possesses certain characteristic properties like malleability, ductility, shiny appearance, and so on. On the other hand, a nonmetal can be characterized by its peculiar properties like brittleness, low density, low melting point, and so on.
(b)
Interpretation:
Whether metal or nonmetal possess the property of colorless gas is to be stated.

- Which elements have molecules as their basic units?(a) helium (b) oxygen(c) iron (d) brominearrow_forwardGive the names of appropriate element for (a)~(d) in the passages below. (1) (a) and (b) are elements that belong to period 5 and 6 in the periodic table, respectively. Both simple substances are solid under room temperature. To an aqueous solution containing cations of (a) and (b), dilute hydrochloric acid was dropped to produce white precipitate. Upon rinsing with boiling water, the precipitate was partially dissolved. (2) Both (c) and (d) are elements that produce stable trivalent cations in an aqueous solution. To an aqueous solution containing (c) and (d) as trivalent cations, aqueous ammonia was dropped to produce a gel-like precipitate. Upon the addition of concentrated aqueous sodium hydroxide, the precipitate was partially dissolved and the majority of (c ) was transferred to the supernatant.arrow_forwardThe noble gas in the second period..arrow_forward
