Answer:

Explanation:
If l = 3, the electrons are in an f subshell.
The number of orbitals with a quantum number l is 2l + 1, so there
are 2×3 + 1 = 7 f orbitals.
Each orbital can hold two electrons, so the f subshell can hold 14 electrons.

Answer:
The frequency of the photon is 7.41*10¹⁶ Hz
Explanation:
Planck states that light is made up of photons, whose energy is directly proportional to the frequency of radiation, according to a constant of proportionality, h, which is called Planck's constant. This is expressed by:
E = h*v
where E is the energy, h the Planck constant (whose value is 6.63*10⁻³⁴ J.s) and v the frequency (Hz or s⁻¹).
So the frequency will be:

Being E= 4.91*10⁻¹⁷ J and replacing:

You can get:
v= 7.41*10¹⁶
= 7.41*10¹⁶ Hz
<u><em>The frequency of the photon is 7.41*10¹⁶ Hz</em></u>

Answer:
1) polar
2)polar (not too sure about this one)
3)nonpolar
Answer:
Ionic bonds transfer electrons and covalent bonds share electrons.
Explanation:
Ionic bonds tend to transfer electrons completely. Take NaCl for example.
Cl has 7 valence electrons.
Na has 1 valence electron.
To stabilize themselves, either with a full 8 shells or full outer shell, Cl wants 1 electron and Na wants to lose 1 electron. So when NaCl forms, Na donates its electron to Cl.
In a covalent bond, the electrons are shared. Water can be used as an example. The electrons in water usually are around the oxygen, but sometimes it is around the hydrogens.
<u>Answer:</u> The layer from where particles of air escape into space is exosphere.
<u>Explanation:</u>
The atmosphere is divided into layers. There are 5 main layers of atmosphere, which are: Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.
- Troposphere is the lowest layer of the atmosphere where most of the weather occurs.
- Then comes the Stratosphere which is about 50 km above the Earth's surface. It contains most of the ozone which is present in the atmosphere.
- Then comes the Mesosphere which starts from 50 km and extends upto 85 km from the Earth's surface.
- Then comes the Thermosphere which starts from 90 km and extends to between 500 km and 1,000 km.
- Exosphere is the last layer of the atmosphere, through which anything escapes the atmosphere to space. This layer extends upto 10,000 km from the Earth's surface.
Hence, the layer from where particles of air escape into space is exosphere.
