What is the term for a symbolic method of expressing the composition of an atomic nucleus?
atomic number
What is the atomic number for stone?
Stone is a composition of various elements and thus does not have an atomic number. Its constituents, however, do.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
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.
What is the term for a symbolic method of expressing the composition of an atomic nucleus?
atomic number
What type of nuclear decay results in the atomic number increasing by one with no change in mass?
Beta- decay result in an increase of atomic number by one, with no resulting change in the atomic mass number.There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number, per se, does not change.

How do the atomic number change?
The atomic number of an element is FIXED it can not normally be changed. However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
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.
Does the atomic number changes when an ion is formed?
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.
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
