Yuri [45]3 years ago
5 0

Answer:

Dalam fisika atom dan kimia kuantum, konfigurasi elektron adalah susunan elektron-elektron pada sebuah atom, molekul, atau struktur fisik lainnya. Secara formal, keadaan kuantum elektron tertentu ditentukan oleh fungsi gelombangnya, yaitu sebuah fungsi ruang dan waktu yang bernilai kompleks.

Describe how light is emitted from an atom. A) As protons absorb energy they travel from the nucleus through the atom emitting l
vovangra [49]

Answer is: D) Light is emitted from an atom as an electron falls from an excited state to the ground state releasing a photon.

Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).

When electron jump from higher to lower energy level (shell), it emitting (releasing) energy.

For example, when the electron changes from n=4 (fouth shell) to n=2 (second shell), the photons are emitted.

Albert Einstein (1879-1955) proposed that a beam of light is a collection of discrete wave packets (photons) with energy hν, where h is Planck constant and ν is frequency.

The photons have a characteristic energy proportional to the frequency of the light.

Minimum frequency or the threshold frequency is energy below which no photoelectrons are emitted.  

Above the minimum frequency, energy depends on the frequency of the light, not on the intensity of the light.

Which substance would have the highest melting point, based on electronegativity?
kenny6666 [7]

Water, H₂O, will have the highest melting point.

Explanation:

So here we have listed the hydrides of oxygen, sulphur, selenium and tellurium.

From this elements oxygen have the highest electronegativity and as a consequence the oxigen hydride (water, hydrogen dioxide) it is able to form hydrogen bonds between molecules. So you need more energy to overcome the interactions between molecules in water that for the other compounds.

Water, H₂O, will have the highest melting point between the listed hydrides.

Carbon-12 contains 6 protons and 6 neutrons. The radius of the nucleus is approximately 2.7 fm (femtometers) and the radius of t
Slav-nsk [51]

Explanation:

Let us assume that volumes is equal to spheres  volume of nucleus.

fm = femto meter = 10^{-15}

pm = pico meter = 10^{-12}

Hence, calculate the volume as follows.

          V = \frac{4}{3} \times \pi \times r^{3}

              = \frac{4}{3} \times 3.14 \times (2.7)^{3}

              = 82.4481 fm^{3} (cubic femtometers)

or,          = 82 fm^{3}

Now, we will calculate the volume of the atom as follows.

          V = \frac{4}{3} \times \pi \times r^{3}

             = \frac{4}{3} \times 3.14 \times (70)^{3}

             = 1436758.4 pm^{3} (cubic picometers)

thus, we can conclude that volume of the nucleus is 82 fm^{3}  and volume of the atom is 1436758.4 pm^{3}.
