Superconductors are materials that transfer energy with no resistance. Metals are usually the best conductors.
Superconductivity is a phenomenon characterized by zero electrical resistance at below critical temperatures. Metals are the best conductors because the molecules inside them are tightly packed, which allows electricity to travel efficiently.
Water is also a good conductor because of the ions and minerals in it. However, water itself is not a conductor of electricity.
Like dissolves like
so water is polar
CCl4 is nonpolar
LiCl is polar
CH4 is nonpolar
PCl6 is nonpolar
so LiCl would dissolve
No it is affected by temperatures .
The answer to this question would be: alkaline earth metal
Alkali earth metal is the second column group of the periodic table. In this group, the element has 2 extra electrons in their outer cells. That is why most of this metal has 2+ charge.
Their neighbor is the alkali metal which was the first column of the periodic table. The name is similar so don't confused and mix them each other.

The energy of a photon is
E=hf
Where
E = Energy
h = Planck's constant (6.62607004Ă—10â’34 J s)
f = frequency of photon.
So plug in the known values
E = 6.62607004Ă—10â’34 J s * 7.03 x 10^14 1/s
E = 4.65812724x10^-19 J
Since we only have 3 significant figures, the rounded result is
E = 4.66x10^-19 J</span>
