What else can I help you with?
Does the atomic number increase when moving left to rt on periodic table?
Yes.
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.
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 does the atomic radius of an atom increase?
the radius of an atom gets larger when moving left to right across the Periodic Table because elements gain protons and electrons- the increase in charge brings the atom radius in
When moving down the middle of the periodic table is there an decrease in reactivity?
In general, moving down the middle of the periodic table results in a decrease in reactivity for transition metals. This is because as you move down a group, the valence electrons are further away from the nucleus, making it harder for the atom to lose or gain electrons and therefore lowering its reactivity.
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.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
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.
Moving tree branches to and fro is which type motion?
Periodic Motion
When moving across a period in the periodic table?
The atomic number increases
What is the trend of reducing property within a group and within a period?
When moving across a period from left to right on the periodic table, properties tend to increase up to group 14 and then decrease. Within a group, as you move down, the properties generally increase due to the addition of extra electron shells.
