Polarity refers to the pull of electrons. Some elements like Fluorine and Oxygen pull electrons closer to them in their bonds (electronegativity), meaning they don't share them equally. So if they pull them closer, there is polarity in the molecule because there's a pull of electrons between atoms.

Polar molecules are molecules are essentially have no molecular symmetry. 

Nonpolar molecules are molecules that have molecular symmetry.

Water is a very basic example of a polar molecule.

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light
harina [27]

Answer:

Explanation:

In photoelectric effect , radiation of some energy is made to fall on metal plate which results in the ejection of electrons by the metal plate . The kinetic energy of electrons comes from the energy of radiation falling on metal plate . Some of energy of radiation falling on metal plate is used in the process of bringing the  electron to  the surface and it is called threshold energy . The radiation must have at least this energy to see to it that electrons are ejected .  and the rest of the energy of radiation is used in imparting kinetic energy to the  electron .

The red light radiation has least energy so it is least likely to eject electrons from metal plate and produce photoelectric effect .

What is the quantum number set of the ground-state electron that is found in lithium (Li) but not in helium (He)?
statuscvo [17]
The electron configuration of lithium atom is: Li:[He]2s^1

The number "2" is the value of the principal quantum number "n". Letter "s" is associated with the value of secondary quantum number "l" and it is equal to zero. The value of "m" (or magnetic quantum number) is zero too. The quantum number set for the highest energy electron will be (2, 0, 0, 1/2).

A gas at STP occupies 22.4 L if the temperature is changed to 260 K and the pressures changed it to 0.50 ATM what will the new v
asambeis [7]

Answer:

The new volume will be 42, 7 L.

Explanation:

We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. The conditions STP are: 1 atm of pressure and 273 K of temperature.

P1xV1/T1 =P2xV2/T2

1 atmx 22,4 L/273K = 0,5atmx V2/260K

V2=((1 atmx 22,4 L/273K )x 260K)/0,5 atm= 42, 67L
