When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
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.
Is it true Moving across a row of the periodic table the atoms tend to get bigger?
Yes, as you move across a row (period) of the periodic table from left to right, the atomic radius tends to decrease. This is due to the increasing effective nuclear charge, which pulls the electrons closer to the nucleus, making the atoms smaller.
Moving across a period on the periodic table from left to right?
Moving across a period from left to right, the atomic number of the elements increases. This results in an increase in the number of protons and electrons, leading to a greater nuclear charge. As a result, the size of the atoms decreases while the electronegativity and ionization energy increase.
When moving across a period in the periodic table?
The atomic number increases
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.
When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
When you read across a row on the periodic table what happens?
When you read across a row on the periodic table, you are moving from one element to the next in order of increasing atomic number. This means that each element has one more proton in its nucleus than the element before it in the row. This results in a gradual increase in the number of electrons and a predictable pattern of chemical properties.
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?

Yes, as you move across a row (period) of the periodic table from left to right, the atomic radius tends to decrease. This is due to the increasing effective nuclear charge, which pulls the electrons closer to the nucleus, making the atoms smaller.
What is the conductivity of calcium carbonate?
Calcium carbonate is an insulator and has low electrical conductivity due to the absence of free-moving electrons in its structure. This means that it does not conduct electricity well in its solid form.
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.
Moving across a period on the periodic table from left to right?
Moving across a period from left to right, the atomic number of the elements increases. This results in an increase in the number of protons and electrons, leading to a greater nuclear charge. As a result, the size of the atoms decreases while the electronegativity and ionization energy increase.
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.
