What else can I help you with?
When an unstable isotope breaks down but doesn't change to another element the atomic number always?
The atomic number is unchanged.
When a beta particle is ejected from a nucleus the nucleus then has a greater what?
When a beta particle is ejected from a nucleus, the nucleus then has a greater atomic number. This occurs because a neutron in the nucleus is converted into a proton during the beta decay process, resulting in an increase in the number of protons. Consequently, the element changes to the next higher element on the periodic table while the mass number remains unchanged.
When an unstable krypton nucleus undergoes beta decay the nucleus formed is that of?
When an unstable krypton nucleus undergoes beta decay, it transforms into a stable rubidium nucleus. In beta decay, a neutron in the krypton nucleus is converted into a proton, resulting in an increase of one atomic number while the mass number remains unchanged. This process changes the element from krypton (atomic number 36) to rubidium (atomic number 37).
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.
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 within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
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.
What number increases in the periodic table?
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
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.
What factors contribute to the decrease in ionization energy within a group in the periodic table as the atomic number increases?
as atomic number is increase the size of the atom goes on increasing as more number of electron is added to the outer most orbit so the nuclear force exerted by the nucleus on electron is less so the affinity to loose electorn is more as the atomic number is increase that is the reason ionization energy decrease with increase in atomic number
What trends do you notice about the atomic number and atomic mass as you move left to right across the table?
they increase by one going from left to right totally a guess
Atomic number increases from Be to Ba why?
The increase in atomic number from Be (beryllium) to Ba (barium) is due to the addition of more protons in the nucleus of the atom. Each element has a unique number of protons, and as the atomic number increases, more protons are added, leading to the formation of elements with higher atomic numbers in the periodic table.
