What is the trend in period 2 ionization energy across the elements?

The trend in period 2 ionization energy across the elements increases from left to right.


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.


Does electronegativity increase in periodic trend?

Yes, as you move from left to right across the period.


What is the general trend in first ionization energy?

increases from left to right across a 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.
