Electronegativity increases when going right along a period and decreases when going downwards along a group.
One can recognize a periodic trend on the Periodic Table by observing properties of different elements from the left side to the right side of the periodic table.
Elements on the periodic table follow a trend where their properties show a periodic repetition based on their atomic number. This trend is known as periodicity and is the basis for organizing elements into groups and periods based on their similar characteristics.
electronegativity
Electronegativity generally increases across a period from left to right on the periodic table due to the increasing nuclear charge, which attracts bonding electrons more strongly. Conversely, it tends to decrease down a group as the distance between the nucleus and the valence electrons increases and the shielding effect from inner electrons reduces the nucleus's pull on bonding electrons. Consequently, elements in the upper right corner of the periodic table, like fluorine, exhibit the highest electronegativity.
Studying physical and chemical properties of chemical elements it is possible to recognize some trends in the periodic table.
