As mentioned above, the characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).
N=5.0 mol
m=3.2 kg
C=n/m
C=5.0/3.2≈1.6 mol/kg
“<u>Aluminum</u>” and “<u>Nitrogen</u>” form an ionic bond.
Option: D
<u>Explanation</u>:
Aluminum and nitrogen are most likely to form an “ionic bond” among given pairs of elements in form of aluminum nitride. AlN is partially covalent and also show ionic characteristics as N needs 3 electrons to fill outer shell and Al has 3 electrons in valence shell. Hence
is cation and
is anion and have “electrostatic force” of attraction between these oppositely charged ions. Here ionic behavior is seen as nitrogen is more “electronegative” hence attract the shared pair of electrons which is earlier responsible for partial covalent bond formation.
Answer: Option (a) is the correct answer.
Explanation:
A chemical formula which represents proportions between the elements present in a compound is known as empirical formula.
When chemical or molecular formula is able to be reduced to smaller whole-number ratio of the elements then both molecular and empirical formulas are considered to be the same.
Relation between molecular formula and empirical formula is as follows.
Molecular formula = n × Empirical formula
where, n is an integer.
Chemical formula of acetic acid is
.
Chemical formula of formaldehyde is
. It is the smaller whole-number ratio of molecular formula of acetic acid.
Chemical formula of Benzaldehyde is
.
Chemical formula of glucose is
.
Thus, we can conclude that formaldehyde molecules has/have the same empirical formula as acetic acid (
).
Sodium, Oxygen, and Hydrogen are found in NaOH. Na=Sodium, O=Oxygen, H=Hydrogen.
