Answer:
See explanation
Explanation:
In each chlorine atom, there are seven valence electrons. Recall that each chlorine atom only needs one electron in order to achieve the stable octet structure.
As a result of this, the chlorine atoms in Cl2 share two electrons contributed by each of the bonding atoms. By so doing, each atom achieves the stable octet as required by the octet rule.
Answer:
1. Mixture
2. Compound
3. Compound
4. Element
Explanation:
Number 1 shows two completely different types of compounds in the same space, so it is a mixture.
Numbers 2 and 3 are compounds because there aren't different types compounds as in Number 1, but the same compound repeated. 2 is a compound because while all of the circles are the same element, they are connected. O2 for example, oxygen, is a compound.
Number 4, finally, is all of the same substance, non-connected, so it shows an element.
