Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
alpha particle, He nucleus
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
When radium emits an alpha particle the resulting nucleus has atomic number?
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
This is emission of an alpha particle which is a helium nucleus. Thus the atomic number decreases by two and the atomic weight by four, in such a radioactive decay
What happens to the atomic number when the nucleus releases a beta particle?
When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 1.
What particle does the atomic number equal in the nucleus?
The number of Protons in the nucleus determines the atom's Atomic number.
What happens to a radioactive nucleus when it emits gamma ray?
It's atomic number decreases by 2 (because it has lost two protons) but as an alpha particle is two protons and two neutrons the Atomic Mass decreases by 4.
When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?
The atomic number decreases by one for each beta particle
What does An alpha particle has the same mass and atomic number as?
Helium nucleus
That particle that gives an element its atomic number is in this part?
The atomic number is determined by the number of protons, which are located in the nucleus.
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
Radioactive decay occurs when the nucleus ejects the?
Radioactive decay occurs when the nucleus of unstable atoms eject protons, positrons or electron in order to attain a stable atomic structure. This yields new elements with reduced atomic number.
