Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,

                Less than 0.4 then it is Non Polar Covalent
                
                Between 0.4 and 1.7 then it is Polar Covalent 
            
                Greater than 1.7 then it is Ionic

For C and N,
                    E.N of Nitrogen      =   3.04
                    E.N of Carbon        =   2.55
                                                   ________
                    E.N Difference             0.49          (Weakly Polar Covalent)

For N and S,
                    E.N of Nitrogen      =   3.04
                    E.N of Sulfur          =   2.58
                                                   ________
                    E.N Difference             0.46           (Weakly Polar Covalent)

For K and F,
                    E.N of Fluorine       =   3.98
                    E.N of Potassium   =   0.28
                                                   ________
                    E.N Difference             3.70          (Ionic)

For N and N,
                    E.N of Nitrogen      =   3.04
                    E.N of Nitrogen      =   3.04
                                                   ________
                    E.N Difference             0              (Non Polar Covalent)

FrozenT [24]
A colloid has the particles that have the ability to scatter light called the Tyndall effect named after the scientist named Tyndall. A suspension has large suspended particles that settle out at the bottom of the container. A solution has small particles that are evenly distributed throughout. Hence the answer is choice 2.

Calculate the frequency of light having a wavelength of 425nm. remember that 1nm=1×10−9m
Gnom [1K]

The frequency of light having a wavelength of 425nm will be 70588 × 10^{14} Hz.

The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places  in the consecutive cycles.

Given data:

wavelength = 425nm = 425 * 10^{-9} m

Frequency can be calculated by using the formula;

Frequency =  speed of light / wavelength

Frequency = 3 × 10^{8} m/s / 425 × 10^{-9} m = 7,0588 × 10^{14} Hz.

Therefore, the frequency of light having a wavelength of 425nm will be 70588 × 10^{14} Hz.

For the 52nd electron must pair with one of the<br> electrons in the 5p orbital.
Umnica [9.8K]

Answer:

This question is incomplete

Explanation:

This question is incomplete, however, the element that has 52 electrons only is Tellurium (Te) and when the electronic configuration of elements with more than 52 electrons are written, the 52nd electron is indicated/paired the same way the 52nd electron of Te is indicated/paired. Hence, while writing the electronic configuration of Te, it is written as

[Kr] 4d¹⁰ 5s² 5p⁴ where [Kr] is the electronic configuration of krypton. Based on this, we can deduce that the 52nd electron will be in the first orbital of the P subshell (as attached in the picture). This is because when indicating the electrons in the subshell, one electron will be spread across each orbital and if any electron is still remaining, it will be added starting from to the first orbital of the subshell, however no two electrons in an orbital in a subshell can have the same spin and hence must face opposite direction based on pauli's exclusion principle (as seen in attached); thus for the 5p-orbital of elements with 52 or more electrons, when one electron each is represented in each box (3 boxes in total) in the 5p-orbital, the remaining electron is paired with the the first electron in the first box of the 5p-orbital
