What is the exception to the trend of increasing ionization energy across a period in the periodic table?
The exception to the trend of increasing ionization energy across a period in the Periodic Table occurs when transitioning from group 2 to group 3 elements. This is because the group 3 elements have a slightly lower ionization energy compared to the group 2 elements due to the added stability of having a half-filled or fully-filled subshell.

What trend it does the first ionization energy follow going across the periodic table?
The first ionization energy tends to increase across a period from left to right on the periodic table. This is due to the increasing nuclear charge and decreasing atomic radius, which leads to a stronger attraction between the electrons and the nucleus.
How do you recognize a periodic trend on the periodic table?
A periodic trend is recognized by observing how a property changes as you move across or down the periodic table. If the property shows a repeating pattern or periodicity, such as consistently increasing or decreasing values at regular intervals, then it is likely a periodic trend. Common examples include atomic radius increasing down a group or ionization energy increasing across a period.
What are the exceptions for ionization energy in the periodic table?
Exceptions to the general trend of increasing ionization energy across a period in the periodic table occur when there is a half-filled or fully-filled subshell, which results in increased stability and lower ionization energy. This is known as the "half-filled and fully-filled subshell stability" rule.
How does Ionization Energy behave along the Periodic Table?
Ionization energy generally increases as you move from left to right across a period in the periodic table due to increasing nuclear charge and decreasing atomic size. It tends to decrease as you move down a group due to increasing distance of the outermost electron from the nucleus. This trend can be slightly affected by electron configuration and shielding effects.
What are the exceptions to the general trend of increasing first ionization energy across a period in the periodic table?
Exceptions to the general trend of increasing first ionization energy across a period in the periodic table can occur due to factors such as electron configuration and atomic size. Elements like oxygen and nitrogen have lower first ionization energies than expected due to electron repulsion in their half-filled or fully-filled orbitals. Additionally, elements in the transition metals group may have lower first ionization energies due to the shielding effect of inner electrons.

What to atomic properties have an increasing trend as you move across the periodic table?
As we move across a period, electronegativity increases. Ionization enthalpy also increases because of increasing nuclear charge.
How can you determine whether ionization energy is a periodic function of atomic number?
Ionization energy is a periodic function of atomic number because it follows periodic trends in the periodic table. As you move across a period from left to right, ionization energy generally increases due to increasing nuclear charge. Similarly, as you move down a group, ionization energy generally decreases due to increasing atomic size. These trends repeat as you move through each period, making ionization energy a periodic function of atomic number.

How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
Which has a greater ionization energy beryllium or germanium?
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
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.
What is the trend ionization energy?
The trend in ionization energy generally increases across a period from left to right due to increasing nuclear charge. Within a group, ionization energy tends to decrease from top to bottom due to increasing atomic size.
From left to right across the second period of the periodic table?
The second period of the periodic table contains elements from lithium to neon, in increasing atomic number order. These elements have increasing numbers of protons and electrons as you move from left to right across the period, resulting in changes in properties such as atomic size and reactivity.
