B. positively charged.
C. negatively charged.
D. not part of an electrolyte.
Answer:
The correct answer is option B. positively charged.
Explanation:
Hello!
Let's solve this!
When an atom yields its electrons, it yields part of its negative charge. Therefore, it immediately transforms into a positively charged ion.
This positively charged ion is called cation.
We conclude that the correct answer is option B. positively charged.
(2) the iron loses its metallic properties
(3) the sulfur gains magnetic properties
(4) the sulfur gains metallic properties
The mixture of iron sulfide formed is non-magnetic wherein iron looses its magnetic properties.
The properties of compound are different from those of the elements from which it is formed. The reason to this is when elements combine to form compounds ,the properties of elements are completely changed and have completely new set of properties.
When iron which has magnetic properties forms a mixture with sulfur iron sulfide is formed,which is non-magnetic.Here, the iron looses it's magnetic properties as it forms compounds with sulfur.
On combining with sulfur, compound formed is iron sulfide with no magnetic properties .Thus on moving the magnet over this mixture does not attract any iron particle towards it as the properties are completely altered when compounds are formed.

Answer:
Molecular bonding cannot occur without electrons.
Explanation:
In order to be 100% correct, the answers should be electrons, protons and neutrons. Since moleculas are formed by atoms and atoms are formed by electrons protons and neutrons.
However, if we consider only the bonding itself, the most important atomic particle is the electron. Molecular or convalent bonding happens when atoms share electrons pairs to reach stability.
