Answer:
A neutral Beryllium atom has two (2) valence electrons
Explanation:
<em>Beryllium, Be,</em> is a group 2 element on the periodic table. Its atomic number is 4.
Generally, atomic number equals number of electrons, which means a neutral Beryllium atom contains four (4) electrons: two (2) in the inner shells and 2 in the outer shell (valence electrons), which can take part in a chemical reaction and participate in chemical bonding.

If she doesn't like you, she doesn't like the real you, therefore you don't deserve her! lol
Magnetic separation is a method that uses magnetic force to remove the magnetically sensitive material from a mixture. Because iron is attracted by magnets, this is the ideal method for separating sand and iron fillings.
Magnetism was the physical attribute that allowed this combination to be separated. I used the magnet to separate the iron filing from the sand in the mixture. The magnet attracted the iron filings but not the sand. We were able to separate the iron filings from the sand as a result of this.
Because iron is magnetic while the other two are not, a magnet may be used to pull the iron filings out of the mixture while leaving the salt and sand. Sand is not water-soluble, although salt is. This implies they may be combined in water and swirled together. The salt dissolves, but the sand does not.

Answer:- B- 
Explanations:- Sharing of electrons takes place between non metals and the bond formed by the sharing of electrons is known as covalent bond. In first choice we only have a zinc metal and so no sharing of electrons would be possible here.
In third choice we have NaCl. Na is a metal and Cl is a non metal. The property of metals is to transfer its valence electrons to the non metal and the bond formed is known as ionic bond. So, third choice is also not correct.
In choice B we have sulfate ion that has sulfur and oxygen atoms and both of these are non metals. So, sharing of electrons is present here between the S and O atoms and covalent bonds are formed.
So, choice B- is the right answer.
