Answer:
uhhh not really i don't even know what that is LOL
Answer:
H-H < C-H < O-H < F-H
Explanation:
The polarity of a bond is the difference in the electronegativity of the elements. This property is the tendency of the atom to gain an electron and form an anion, or when in covalent bond (sharing electrons), to have the electron close to it.
As higher is the atomic radius, as difficult it is to the atom to gain an electron because the attractive force will be less effective. So, the electronegativity increases from the bottom to top, and from the left to right in the periodic table.
So, when the bond is between the same element, the polarity is 0, such as H-H. H has a low electronegativity, then it comes C, O, and F, so, the order of increasing of polarity is:
H-H < C-H < O-H < F-H
Answer:
C
Explanation:
electronic waves transmits energy but mechanical waves require a medium in order to transport their energy from bgg one place to another.
Answer: Option (D) is the correct answer.
Explanation:
Atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.
So, in order to attain stability it tends to gain one electron from a donor atom. Therefore, a chlorine ion is formed as
.
As it gains only one electron that is why, -1 charge occurs.
Whereas Ar is a noble gas with atomic number 18. As it has completely filled octet so it will be unreactive in nature as it is already stable.
Similarly, He is also a noble gas so it is unreactive in nature.
Atomic number of boron (B) is 5 with electronic distribution 2, 3. So, in order to attain stability it needs to lose 3 electrons.
Thus, we can conclude that Cl is the atom which tends to gain 1 valence electron from another atom in order to become stable.
