We have to know which do not violet octet rule.
The central atom in SF₄ does not violate the octet rule. the central atom in CF₄ does not violate the octet rule.
As per octet rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valence shell.
The central atom S of SF₄ contains 8 electrons in the valence shell. Also, C atom of CF₄ contains 8 electrons in the valence shell.
ICl₄⁻ contains 9 electrons in the outermost shell.
Answer:
The strength of a bond depends on the amount of overlap between the two orbitals of the bonding atoms
Orbitals bond in the directions in which they protrude or point to obtain maximum overlap
Explanation:
The valence bond theory was proposed by Linus Pauling. Compounds are firmed by overlap of atomic orbitals to attain a favourable overlap integral. The better the overlap integral (extent of overlap) the better or stringer the covalent bond.
Orbitals overlap in directions which ensure a maximum overlap of atomic orbitals in the covalent bond.
Answer:
B. decrease.
Explanation:
Because size of atom increases so it is easy to remove electron
Remember that as per the law of ideal gases the number of molecules of a gas is proportional to the volume, which means that at the same temperature and pressure, the same amount of molecules will have the same volume.
You can deduct that from pV = nRT
From there if p, and T are constants:
V = (a constant) * n
So, the same number n, will give the same number V.
Then, 3.0 molecules of H2(g) will have the same volume that 3.0 molecules of any other gas, under same pressure and temperature, assuming ideal gases.
So, the answer is the third option, 3.0 L of CH4(g).
The correct answer among the choices is option A. The term that defines the following: grams of solute divided by 1,000,000 grams of solution is called ppm. This is one
way of expressing concentration. Parts per million is also equal to 1 milligram of solute per kilogram of
solution.
