<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Valence electrons are defined as the electrons which are present in the outermost shell of an atom. Outermost shell has the highest value of 'n' that is principal quantum number.

Sulfur is the 16th element of the periodic table having 16 electrons. The electronic configuration of this element is: 1s^22s^22p^63s^23p^4

The number of electrons in first shell (n = 1) : 2

The number of electrons in second shell (n = 2) : (2 + 6) = 8

The number of electrons in third shell, outermost shell (n = 3) : (2 + 4) = 6

The number of valence electrons in sulfur atom are 6

Hence, the correct answer is Option D.

You can obtain a rough estimate of the size of a molecule with the following simple experiment: Let a droplet of oil spread out
mina [271]

Answer:

The diameter of the oil molecule is 4.4674\times 10^{-8} cm .

Explanation:

Mass of the oil drop = m=9.00\times 10^{-7} kg

Density of the oil drop = d=918 kg/m^3

Volume of the oil drop: v

d=\frac{m}{v}

v=\frac{m}{d}=\frac{9.00\times 10^{-7} kg}{918 kg/m^3}

Thickness of the oil drop is 1 molecule thick.So, let the thickness of the drop or diameter of the molecule be x.

Radius of the oil drop on the water surface,r = 41.8 cm = 0.418 m

1 cm = 0.01 m

Surface of the sphere is given as: a = 4\pi r^2

a=4\times 3.14\times (0.418 m)^2=2.1945 m^2

Volume of the oil drop = v = Area × thickness

\frac{9.00\times 10^{-7} kg}{918 kg/m^3}=2.1945 m^2\times x

x= 4.4674\times 10^{-10} m= 4.4674\times 10^{-8} cm

The thickness of the oil drop is 4.4674\times 10^{-8} cm and so is the diameter of the molecule.

Which is composed of alkynes?
telo118 [61]
The correct answer is letter (A) Acetylene. Acetylene is the most simplest form of alkyne and at the same time a hydrocarbon. It is unsaturated because of the presence of only two carbon atoms that are bonded together in a triple bond. I<span>n its pure, it is unstable and thus, it is usually held and handled as a solution.</span>
