The trend across a period refers to how a property of elements changes as you move from left to right across a row in the Periodic Table. For example, in terms of atomic size, the trend across a period is generally a decrease due to the increasing number of protons in the nucleus pulling the electrons closer.

What trend in ionization energy occurs going across a period on the periodic table and why?
Ionization energy generally increases across a period from left to right on the periodic table. This trend occurs because as you move across a period, the number of protons in the nucleus increases, resulting in a greater nuclear charge. This stronger attraction between the nucleus and the outer electrons requires more energy to remove an electron, thus increasing the ionization energy.
The periodic trend for electronegativity is similar to what other trend?
The trend for first ionization energy
What trend in ionization energy do you see as you go across a period row on the periodic table what causes this trend?
Ionization energy generally increases as you go across a period on the periodic table. This is because as you move from left to right, the effective nuclear charge increases, leading to stronger attraction between the nucleus and the electrons, making it more difficult to remove an electron.
How does Electronegativity trend across the periodic table?
Electronegativity generally increases from left to right across a period and decreases down a group in the periodic table. This trend occurs because elements on the right side of the periodic table have a greater ability to attract electrons due to increased nuclear charge and effective nuclear charge.
What trend electronegativity do you see across period on the periodic table?
The trend as you move from left to right across a period in the periodic table, the electronegativity increases due to the stronger attraction that the atoms obtain as the nuclear charge increases. Moving down a group, the electronegativity decreases due to the longer distance between the nucleus and the valence electron shell, thereby decreasing the attraction, making the atom have less of an attraction for electrons or protons.
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
What is the general trend in ionization energy?
increases from left to right across a period.
What is the general trend in first ionization energy?
increases from left to right across a period.
Does electronegativity increase in periodic trend?
Yes, as you move from left to right across the period.
What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases
What is the trend electronegative as atomic number increase across the period?
Electronegativity increases across a period. Element becomes more negatively charged.
What do you notice about the boiling points as you move from left to right across the periodic table?
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.
What is the general trend of the melting points of hydrides across the period?
The general trend of the melting points of hydrides across a period is that they decrease from left to right. This is because the electronegativity of the atoms increases across a period, resulting in stronger hydrogen bonding and lower melting points.
What trend in ionization energy occurs going across a period on the periodic table and why?
Ionization energy generally increases across a period from left to right on the periodic table. This trend occurs because as you move across a period, the number of protons in the nucleus increases, resulting in a greater nuclear charge. This stronger attraction between the nucleus and the outer electrons requires more energy to remove an electron, thus increasing the ionization energy.
The periodic trend for electronegativity is similar to what other trend?
The trend for first ionization energy
What trend in ionization energy do you see as you go across a period row on the periodic table what causes this trend?
Ionization energy generally increases as you go across a period on the periodic table. This is because as you move from left to right, the effective nuclear charge increases, leading to stronger attraction between the nucleus and the electrons, making it more difficult to remove an electron.
What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
