The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
What is the radioactive decay of an atom resulting in the decrease in the atomic number with no charge in the atomic mass called?
It is called beta decay. there are two types: 1) posive beta decay in which atomic number decreases. 2) negative beta decay in which atomic number increases.
What is radiums atomic number?
Radium is a none metal element. atomic number of it is 88.
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
What happens to the atomic mass number in a radioactive substance?
In a radioactive substance, the atomic mass number may change as a result of radioactive decay. During radioactive decay, radioactive atoms undergo nuclear reactions, which can lead to the emission of radioactive particles such as alpha or beta particles. These emitted particles can cause a change in the number of protons and neutrons in the nucleus, resulting in a different atomic mass number for the resulting atom or isotope.

The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
What does the number of electrons in an atom do as the atomic number increases?
Increase
What is the radioactive decay of an atom resulting in the decrease in the atomic number with no charge in the atomic mass called?
It is called beta decay. there are two types: 1) posive beta decay in which atomic number decreases. 2) negative beta decay in which atomic number increases.
As you travel down a group the do atomic size increases or decreases?
it increases: for the atomic number indicates the number of protons and neutrons in the atom; these are the weight carrying particles
What happens to the number of electrons in an atom when the atomic number increases?
The atomic number is specific to the element itself - not the quantity. It does not change as you add in more of the element.
Is the mass number of an atom equal to the atomic number?
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
The atomic number of an atom or element describes the number of what?
The atomic number of an atom is also known as the proton number. it is, quite simply, the number of protons in the atoms nucleus - as an atom needs to be equally charged, it is also the number of electrons in an atom however, if an atom is radioactive this is not always true.
What is radiums atomic number?
Radium is a none metal element. atomic number of it is 88.
How many protons does and atom with an atomic of 23 and a mass of 51 have?
An atom with an atomic number of 23 has 23 protons. The only thing that determines the atomic number of an element is the number or protons in its nucleus. The proton count is the sole determinant as to the elemental identity of every atom. An atom with an atomic mass of 51 and an atomic number of 23 has 28 neutrons, as atomic weight - atomic number = number of neutrons. The atom described here is an atom of nickel, and it's nickel-51, which is a radioactive isotope of nickel that we've created in the physics lab.
Why does an atomic number increase?
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
Why does the atomic radius decrease with an increase in atomic numbers within a period?
As the atomic number increases, the number of protons in the nucleus increases or the effective nuclear charge of the nucleus increases. As a result the force exerted by the nucleus on the valence electrons is more or the size of the atom is small.
