Can an electron be found in an exact spot within an atom

1 answer:

3 0

No, it is impossible to determine the exact location of an electron. This is because electrons don't have a definite position, and direction of motion, at the same time and its movements are unpredictable

Why do different latitudes have different temperatures?

liubo4ka [24]

Latitude or distance from the equator. Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.

True or false solids possess a greater level of kinetic energy than gases

Kipish [7]

Answer:

False

Explanation:

Solid particles have the least amount of energy, and gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed.

In a Hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. How many unique charge-p

lutik1710 [3]

Answer:

The total number of charge pair without double counting is 6.

Explanation:

Given that,

Number of proton = 2

Number of electron = 2

We need to calculate the total number of charges in Hydrogen atom

Using formula for number of charges

$n= p+n$

$n =2+2$

$n=4$

Number of charge in pair is

$r = 2$

We need to calculate the total number of possible combination of pairs without double counting

Using formula of combination

$N=_{n}C^{r}$

Where, n = number of charges

r = number of charges per pair

Put the value into the formula

$N=_{4}C^{2}$

$N=\dfrac{4\times3\times 2}{2(4-2)}$

$N=\dfrac{4\times3\times 2}{2\times2}$

$N=6$

Hence, The total number of charge pair without double counting is 6.

Light from a helium-neon laser (λ=633nm) passes through a circular aperture and is observed on a screen 5.80 mm behind the apert

Helga [31]

Explanation:

Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.

So by using the equation of diffraction,

dsinA = nL

SinA is a geometric component it can be written as,

$d\frac{y}{x} = nL$

∵ x is the distance from screen.

∵ y is the half of the width of central maximum.

now by putting the values in mm,

$d\frac{17}{5.80} = 0.000633$

d = 2.15× $10^{-4}$ mm
