The question is incomplete. Complete question is:
Which list represents the classification of the
elements nitrogen, neon, magnesium, and
silicon, respectively?
(1) metal, metalloid, nonmetal, noble gas
(2) nonmetal, noble gas, metal, metalloid
(3) nonmetal, metalloid, noble gas, metal
(4) noble gas, metal, metalloid, nonmetal
.................................................................................................................
Answer: The correct answer is option 2) nonmetal, noble gas, metal, metalloid
Reason:
1) Non-metal are bad conductors of electricity. Also non-metal are electronegative in nature. Hence, among the provided elements, nitrogen satisfied the criteria. Hence, it is a non-metal.
2) Noble gas are the elements which have completely filled outermost shell. Hence, among the provided elements, Neon satisfied the criteria.
3) Metal are good conductors of electricity. Also metal are electropositive in nature. Hence, among the provided elements, magnesium satisfied the criteria. Hence, it is a metal.
4) Metalloid have conductivity better than non-metals but poor than conductors. Hence, among the provided elements, Silicon satisfied the criteria. Hence, it is a metalloid.
Answer:
Write down the phases and what happens during each phase.
Explanation:
Answer is: true.
Demand decreases and competition increases decrease the quantity supplied.
Quantity supplied is the quantity of a commodity that producers are willing to sell at a particular price at a particular point of time.
Quantity demanded is the quantity of a commodity that people are willing to buy at a particular price at a particular point of time.
Quantity demanded can change at the same price depending upon factors like recession, changes in the taste of the consumer.
Competition is rivalry between two or more economic groups.
Answer:
Option C: Observation
Explanation:
The first and foremost step in the process of scientific inquiry is observation. Because, until there is no observation there are no questions to Ask. Having high quality observation is too much valuable in scientific process.
