Answer:
Claim 1
Explanation:
I chose this claim because I believe that when the plates under the earth move or shift, that's what causes an earthquake and when everything starts to shake. If it was the other way around there wouldn't be any reason for an earthquake to start.
hope that helped :)
Answer: The answer is 100%. Hope this helps :)
Explanation:
Group 7
Explanation:
The unknown element belongs to the seventh group on the periodic table of elements.
Ionic bonds are usually formed between metals and nonmetals. They formed by the transfer of electrons from the less electronegative specie to the more electronegative one.
The metals usually lose electron because they are highly electropositive species.
- If we have a magnesium atom with two valence electrons.
- To form ionic bonds, it must transfer the two electrons to another atom.
- The other atom, a nonmetal must be ready to accommodate and receive the donated electrons.
- This ensure that its own octet is complete.
- Group 6 elements requires 2 electrons to have a complete octet.
- They can receive the two electrons
But we were told that there are two atoms of that element for each of the magnesium atom;
the atom must have a capacity of collecting one electron each to be stable.
Such atoms are found in Group 7 on the periodic table.

I will give you two clues just incase:
-Change in temperature-usually when a reaction takes place heat will be absorbed or released which result in a temperature change.-eg: put a piece of sodium in water. you will feel or observe that the temperature is increased
-Change in colour-Some times we see a colour change in the media when a reaction takes
How important each one is depends on what you are learning about a chemical reaction. Hope I helped!
