Going down a group, the number of valence electrons remains the same, but these electrons get farther and farther away from the nucleus. Thus, they are not as tightly held and the ionization energy decreases. Moving from left to right along a period, the electrons are the same distance from the nucleus, but the number of protons are increasing in the nucleus, thus holding those electrons more tightly. Thus, the ionization energy increases.
Ionization energy decreases down a group because atomic size increases, leading to weaker attraction between the nucleus and valence electrons. Along a period, ionization energy increases because the effective nuclear charge increases, making it harder to remove an electron.

What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
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.
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 accounts for the general trend in the first ionuization energy of the elements within a period?
The general trend in the first ionization energy within a period increases from left to right due to an increasing effective nuclear charge. As protons are added to the nucleus, the attraction between the positively charged nucleus and the negatively charged electrons increases, making it more difficult to remove an electron.
What happens to ionization energy when atomic number increases or decreases in a period?
Ionization energy generally increases as atomic number increases in a period. This is because as the number of protons increases, the nucleus exerts a stronger pull on the outermost electrons, making it more difficult to remove them. Conversely, as atomic number decreases in a period, ionization energy generally decreases because there are fewer protons in the nucleus to attract the electrons.
How does ionization energy of elements in the same period change?
Ionization energy increases as you go across a period, but as you go down a group it decreases.
As you go from left to right across a period the first ionization energy generally decreases or increases?
increases.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
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 Trend in first ionization energy across a period?
As one proceeds down the group 7A elements, the first ionization energy decreases. this means that the outermost electron is more readily removed as we go down a group.
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.
Describe the trends in first ionization energy within groups and across periods in the periodic table Provide examples?
Within a group, first ionization energy generally decreases as you move down the group due to increasing atomic size and shielding effects. Across a period, first ionization energy generally increases due to increasing nuclear charge and effective nuclear charge. For example, within Group 2 (alkaline earth metals), the first ionization energy decreases as you move down the group from Be to Ra. Across Period 3, the first ionization energy increases from Na to Cl.
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.
Which element in the fifth period has the highest ionization energy?
The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest 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.
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.
