The number of electrons increases with the atomic number. So the electronegativity increases with the atomic number.
Not quite. Electronegativity doesn't consistently increase with atomic number. For example, F is more electronegative than Na, even though Na has a higher atomic number.
As you move up a column of the periodic table, the number of electron shells increases. This leads to a greater distance between the nucleus and the outermost electrons, resulting in larger atomic size. Additionally, the number of protons and electrons also increases, leading to a higher atomic number and different chemical properties.
False. Electronegativity does not increase continuously as atomic number increases. While there is a general trend of increasing electronegativity across a period from left to right on the periodic table, there are exceptions due to factors such as electron configuration and atomic structure.
An increase in atomic number within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
As you move across a period from left to right in the periodic table, the atomic number of the elements increases by one with each element. Electronegativity also increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius, which results in stronger pull on electrons.
As you move from left to right across a period, the number of protons increases, leading to a stronger positive charge in the nucleus. This attracts the electrons more strongly, resulting in a greater effective nuclear charge experienced by the electrons. This increased attraction causes electrons to be pulled closer to the nucleus, leading to a decrease in atomic size.

Electronegativity increases across a period. Element becomes more negatively charged.
Increase
As the nuclear charge increases across a period, the number of protons in the nucleus increases. This leads to a stronger attraction between the nucleus and the electrons in the atom, resulting in a greater effective nuclear charge. This can lead to an increase in the atomic size and higher electronegativity across a period.
Atomic number, ionization energy and electronegativity
1-Atomic size = decreases 2-Ioniztion energy = increases 3-Electronegativity = increases (except Argon) 4-Metallic character = decreases 5-Melting point = first increases then decreases
Towards the bottom, atomic mass increases. Atomic number also increases.
As you move from left to right across a period, the number of protons increases, leading to a stronger positive charge in the nucleus. This attracts the electrons more strongly, resulting in a greater effective nuclear charge experienced by the electrons. This increased attraction causes electrons to be pulled closer to the nucleus, leading to a decrease in atomic size.
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
