Electronegativity generally increases from left to right across a period and decreases from top to bottom within a group on the periodic table. This trend is due to the increasing nuclear charge across a period and the increasing distance between the nucleus and valence electrons down a group.
Electronegativity decreases along a period. This is because atomic radius increases increases, hence nuclear charge decreases.
Yes, as you move from left to right across the period.
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
The atomic weight (not mass) increase from left to right in a period.
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
Electronegativity generally increases from left to right across a period and decreases from top to bottom within a group on the periodic table. This trend is due to the increasing nuclear charge across a period and the increasing distance between the nucleus and valence electrons down a group.
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.

The trend for first ionization energy
one should look for predictable changes and patterns
a numbering system for the Periodic Table. Or a trend that periodically shows up.
A periodic trend is recognized by observing how a property changes as you move across or down the periodic table. If the property shows a repeating pattern or periodicity, such as consistently increasing or decreasing values at regular intervals, then it is likely a periodic trend. Common examples include atomic radius increasing down a group or ionization energy increasing across a period.
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
