Answer:
F
O
N
Mg
Explanation
The key explanation here is that we need to know the trends in electronegativity value increase or decrease across the periods and down the group.
Across the periods, electronegativity is expected to increase. Hence, with the exception of the noble gases, the most electronegative elements are found further right on the periodic table. While electronegativity is expected to increase across the period, it decreases down the group.
Hence, if two elements are in the same group, further down we have the one with the less electronegative value. If two elements are in the same period, further right we have the more electronegative element.
Answer:
it has a fixed volume it can also be compressed
Explanation:
a gases molecules don't move slow because they are not solid and are not compacted.
a gas does not have a fixed shape because there is nothing to hold its shape
0s to 15s: constant speed/zero acceleration
15s to 40s: constant gradient, therefore constant deceleration
