Answer:
Electronegativity increases across the period on a periodic table.
Explanation:
Electronegativity is the ability of an atom to attract electron to itself.
All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.
This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.
Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.
This makes them highly reactive and combine readily with other elements.
The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.
Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.
Gas and radio waves I’m pretty sure is correct
Answer:
I think Mg is correct I am not sure
Answer:
its because atoms are incredibly small its looking for atoms is like placing a blueberry in a foot ball field and looking at it from 10 miles up you cant see that blueberry
