2. Convert the mass of each element to moles. ...
3. Find the ratio of the moles of each element. ..
4. Use the mole ratio to write the empirical fomula
Answer:

Explanation:
From the question we are given
a. He
b. C
c. F
Generally
The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.
Therefore
The order of electron Affinity is give as

Answer and Explanation:
The answer is solution. However, single-phase alloys are solid metal solutions, and colloidal suspensions are homogenous mixtures that are not solutions. Homogenized milk, for example, is a colloidal suspension that technically meets the definition of a homogenous mixture because the milk fats, though immiscible with the whey (the aqueous phase), are tiny beads evenly distributed through the whey, and do not separate according to density, as they do in non-homogenized milk.
Hope this helps. :)
I think its called refraction
Answer:
it will have 1 valence electron as its in the first group in the periodic table.
It will lose electrons as its easier.
The charge will be 1+ as it lost 1 .
