Answer:

It is a fundamental concept that atomic spectra are discontinuous the electron's energy levels are quantized which is a quantum mechanics concept that a system is limited to certain energy states which depends on the particular system being refereed to

Explanation:

Atomic electrons posses only specific energy levels with nothing in between those levels, it can be excited to a higher energy level by gaining the required energy or lose energy in quantized packets to drop to a lower energy level hence the discontinuous spectral lines

What minimum frequency of light is required to ionize boron?
Nadusha1986 [10]

Answer:

frequency  = 8.22 x 10¹⁴ s⁻¹

Explanation:

An electron's positional potential energy while in a given principle quantum energy level is given by Eₙ = - A/n² and A = constant = 2.18 x 10⁻¹⁸j. So to remove an electron from the valence level of Boron (₅B), energy need be added to promote the electron from n = 2 to n = ∞. That is, ΔE(ionization) = E(n=∞) - E(n=2) = (-A/(∞)²) - (-A/(2)²) = [2.18 x 10⁻¹⁸j/4] joules = 5.45 x 10⁻¹⁹ joules.

The frequency (f) of the wave ionization energy can then be determined from the expression ΔE(izn) = h·f; h = Planck's Constant = 6.63 x 10⁻³⁴j·s. That is:

ΔE(izn) = h·f => f = ΔE(izn)/h = 5.45 x 10⁻¹⁹ j/6.63 x 10⁻³⁴ j·s = 8.22 x 10¹⁴ s⁻¹

Enter the electron configuration for the ion most likely formed by phosphorus. Express your answer in the order of orbital filli
Bingel [31]

Answer:

[Ne] 2s2 2p3

Explanation:

Phosphorus will most likely have an ion that will be 3- because it wants to have a full outer shell. Thus, the elctron configuration is: 1s2 2s2 2p6 3s2 3p3.

Explain why the nucleus of an atom is positively charged but the overall charge of an atom is neutral
luda_lava [24]

Answer:

sorry

Explanation:

i'm not a chemistry student

but let me try

it is because the neutron of an atom is -

why the proton and electron is +and- (positive and negative)

so + and - = 0

A force of 3000N is applied on a 20kg ball. Find the acceleration of the ball
Andrews [41]

Answer:

force = 3000N

mass= 20 kg

now

F= ma

3000= 20×a

3000÷20=a

a=15

F= ma by newtons second law of motion
