Answer:

Explanation:
Here, we wnat to get the most electronegative atom
On the periodic table, electronegativity increases across a period and decrease down the group
The elements listed are in the same group
Boron is the first member of the group
Boron is the most electronegative atom in the group
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.
Answer:
The energy of the photon is directly proportional to the frequency of the light emitting the photon.
Explanation:
Energy of the photon is given by expression:

E = Energy associated with the photon
= frequency of the light
h = Planck's constant =
c = speed of the light in vacuum = constant
=Wavelength of the photon

The energy of the photon is directly proportional to the frequency of the light emitting the photon.
