Your question is incorrect. It should be increases rather than decreases. Well it is the proton number (Z) that increases.
Atomic size increases going down a group in the periodic table. This is because additional energy levels are being filled with electrons, leading to an increase in distance between the nucleus and the outermost electron shell.
From left to right and into the upper corner of the periodic table electronegativity increases. Fluorine is the most electronegative element, but the elements in group 18 generally have no electronegativity at all.
Electronegativity generally decreases as you go down a group on the periodic table due to the increasing distance between the nucleus and valence electrons, reducing the attractive force. Across a period, electronegativity generally increases due to the increasing nuclear charge, pulling valence electrons closer and increasing their attraction.
Electronegativity increases from left to right and decreases from top to bottom on the periodic table.
The strength of the metallic bond generally decreases going down a group and increases moving across a period on the periodic table. This is because metallic bonding is influenced by the number of delocalized electrons available to form bonds, which changes with the size and number of valence electrons in atoms as you move within the table.
the energy level increases as we move from top to bottom in the periodic table

Electronegativity increases across (left to right) the periodic table and decreases on going down.
No, the number of electrons increases as you move to the right.

Across a period, electronegativity generally increases due to the increasing nuclear charge, pulling valence electrons closer and increasing their attraction.
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
Electronegativity increases as you move across the periodic table from left to right.
Electronegativity increases from left to right and decreases from top to bottom on the periodic table.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
The atomic number increases. The atomic number identifies a particular element and the elements are arranged in increasing order on the periodic table. Also, the atomic weight generally increases as well.
