When an unstable isotope breaks down but doesn't change to another element the atomic number always?
The atomic number is unchanged.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
Atomic number increases from Be to Ba why?
To go from H to U - nevermind Be to Ba requires an increase in protons, The atomic number is defined by the number of protons
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
When an unstable isotope breaks down but doesn't change to another element the atomic number always?
The atomic number is unchanged.
What happend to the atomic number of an element which emits alpha particle and two beta particle?
THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
What accompanies an increase in atomic number within a specific period?
An increase in atomic number would be accompanied by a decrease in radius, and an increase in electronegativity.
How do atomic numbers and atomic masses increase in the periodic table?
The atomic number and atomic masses increase as you move from left to right.
What happen to atomic number and mass number of nucleus when it emits electron?
"Number" goes up by one, mass stays the same.
What number increases in the periodic table?
Both the atomic number and atomic mass. among many other things. They increase the atomic number because the atomic number IS the number of protons in an atom. They increase the atomic mass because the atomic mass is the number of protons + neutrons in an atom. Basically the main two things..
What does the number of electrons in an atom do as the atomic number increases?
Increase
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
Ifthe atomic number increase what happens to the atomic mass?
Nothing. They are not correlated
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
What is the relationship of ionic radius and atomic number?
They both increase
