Question

what appears to be the trend in electronegativity as you move from left to right in a period? increasing decreasing remains the same

Explanation:

In the periodic table, as we move from left to right across a period, the atomic number increases, meaning the number of protons in the nucleus increases. This leads to a greater effective nuclear charge (the positive charge experienced by the outermost electrons). With a greater effective nuclear charge, the attraction for electrons (electronegativity) increases. For example, in Period 2, from lithium (Li) to fluorine (F), electronegativity values increase. So the trend of electronegativity from left to right in a period is increasing.

Answer:

increasing
