What does the horizontal placing of the elements in the periodic table signify?
It signify the group of the element. For example, the first group is called alkali metals. When it is moving from left to right of the periodic table, the atomic radius decreases, the ionization energy increases, and the electronegativity increases.
What are two trends in the periodic table?
Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.
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.
What is the relationship between elements and the periodic table and ionisation energy?
The relationship between atomic numbers and first ionization energies is that within the same period, as atomic number increases so does first ionization because as nuclear charge increases and atomic radius decreases, electrons become harder to remove. However, within the same group, the first ionization energy decreases as atomic number increases because of the added energy level, the electrons are farther from the nucleus and easier to remove.
Which noble gas has the least number of protons?
Radon (as down a group, the atomic size increases and the ionization energy decreases)
Which decreases with increases atomic number group 2A?
Group IIA metals (alkali earth) become more reactive with non-metals as you go higher in atomic numbers.
How can you determine whether ionization energy is a periodic function of atomic number?
as atomic number increases, ionization energy also decreases

It signify the group of the element. For example, the first group is called alkali metals. When it is moving from left to right of the periodic table, the atomic radius decreases, the ionization energy increases, and the electronegativity increases.
What happens as we move down columns on the periodic table?
As you move down a column (group) in the periodic table, the electronegativity decreases, the ionization energy decreases, the electron affinity decreases, and the atomic radius increases.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
What is the trend found in Period 3 on the Periodic Table as the elements increase in atomic number?
1-Atomic size = decreases 2-Ioniztion energy = increases 3-Electronegativity = increases (except Argon) 4-Metallic character = decreases 5-Melting point = first increases then decreases

How does the ionization energy vary with atomic number within the group?
Ionization energy decreases with the rise of atomic number in a group of periodic table.

When moving left to right across the periodic table the atomic number increases and the atomic radius?
The atomic radius decreases from left to right and increases from top to bottom
