Moving across a period on the periodic table from left to right?
ionization energy
Is it true Moving across a row of the periodic table the atoms tend to get bigger?
yes
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
What happens to the atomic radius when you go from left to right on the periodic table?
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
Describe the trends in first ionization energy within groups and across periods in the periodic table Provide examples?
When moving left to right across the PT the ionization energy increases. As you go down, the ionization energy, decreases.
When moving across a period in the periodic table?
The atomic number increases
Moving across a period on the periodic table from left to right?
ionization energy
Is it true Moving across a row of the periodic table the atoms tend to get bigger?
yes
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.

When moving left to right across the PT the ionization energy increases. As you go down, the ionization energy, decreases.
What happens to the number of neutrons in a typical atom moving from left to right on the periodic table?
From left to right , atomic number increases. Number of neutrons also increases.
Do freely moving valence electrons account for electrical conductivity in metals?
yes they conduct electricity
How do atomic radii change from left to right across a horizontal row of the periodic table and what is the main reason?
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
