This is where you guys are missing it.option A was wrong because non metal like carbon(graphite) do conduct electricity.option B was also wrong because non mental like Carbon (diamond) do have higher density than some of the so called metals like potassium, sodium (which do float on water).option C was also wrong because although some metals like potassium and sodium etc form basic oxide; some metals like lead(Pb), zinc(Zn), tin(Sn) etc form amphoteric oxide. Remember that amphoteric oxides are oxides that have both acidic and basic properties i.e they can behave both as an acid and base.so it's different from basic oxide.option D was also wrong because though some metals like sodium, potassium , Calcium, Iron, zinc, Aluminium etc all these are above hydrogen in the electrochemical series. But some metals like copper, gold, silver, etc are below hydrogen in the electrochemical series. But all non metals are below hydrogen in the electrochemical series.so, as all non metals are below hydrogen in the series, some metals are also below hydrogen. Option E is correct because in any reactions involving oxidation and reduction. Metals( reducing agents) do loss electron(s) while non metals(oxidixing agents) gain electron(s) so option E is correct.
Let's evaluate each statement:
A. Metals conduct electricity while non-metals do not: This is generally true. Metals are good conductors of electricity due to the presence of free electrons, while most non-metals are poor conductors. However, there are exceptions like graphite, a form of carbon (a non-metal), which can conduct electricity.
B. Metals have high density, non-metals have low density: This is generally true, but there are exceptions. For example, osmium is a metal with one of the highest densities, while lithium is a metal with a low density.
C. Metals form basic oxides, non-metals form acidic oxides: This is generally true. Metal oxides are usually basic, and non-metal oxides are usually acidic. However, there are exceptions such as aluminum oxide which is amphoteric (can act as both an acid and a base).
D. In the electrochemical series, metals are above hydrogen while non-metals are below hydrogen: This is not necessarily true. The position of an element in the electrochemical series depends on its standard electrode potential, not whether it's a metal or non-metal.
E. Metals lose electrons while non-metals gain electrons during chemical reactions: This is generally true. Metals tend to lose electrons and form positive ions (cations), while non-metals tend to gain electrons and form negative ions (anions) in chemical reactions.
So, the statements **A**, **B**, **C**, and **E** are generally true with some exceptions, while statement **D** is not necessarily true. Therefore, the most accurate answer would be **E. Metals lose electrons while non-metals gain electrons during chemical reactions** as it holds true without exceptions in the context of ion formation.
Option E is the most appropriate....graphite (non metal) conducts electricity. Diamond (non metal)has a higher density than sodium. Carbon in CO forms neutral oxide and zinc forms amphoteric oxide..copper, gold,silver( metal) are below hydrogen in ECS........option E is correct
elements below hydrogen are all metals
there are copper, Mercury silver and gold
so I think option E is the most appropriate
the question is not correct, it is supposed to be, which of this statement is not true not otherwise.
Metal for example Ca²+ is deficit of two electrons. Which electron does it lose again?
Here is an explanation:
YEP, ACCORDING TO OKWUNZE KENE OPTION A,B IS WRONG,OPTION D IS WRONG bcos non metals are not blow hydrogen in ECS option E is also wrong bcos hydro is technically a nonmetal and can gain electron therefore option C is most likely correct bcos most metals form basic oxide
REF: hydrogen and its compounds and acids,bases in new school chemistry
Metals lose electrons while non-metals gain electrons during chemical reactions: This is generally true. Metals tend to lose electrons and form positive ions (cations), while non-metals tend to gain electrons and form negative ions (anions) in chemical reactions.
PLEASE CHANGE IT
OPTION E IS THE MOST APPROPRIATE
