The result is radon, atomic number 86.
226Ra - alpha particle = 222Rn (radon, a radioactive gas)

The blank is the particle in the nucleus of an atom that carries a positive charge and is counted to identify the atomic number?
Proton.
What does the subatomic particle do?
Protons and neutrons are the components of the atomic nucleus; the number of protons is equal to the atomic number, the most important parameter for a chemical element. Electrons surround the nucleus and are responsible (the last level) for the chemical properties of elements.
When uranium-238 atomic number 92 decays by emitting an alpha particle it becomes?
The atomic number will decrease by 2. An alpha particle is a helium-4 nucleus, and it contains a pair of protons and a pair of neutrons. During alpha decay, an atomic nucleus has its atomic mass decrease by 4, and its atomic number decrease by 2.
When a radioactive isotope emits a its atomic number increases?
a beta particle. the nucleus is made of protons (+) and neutrons. but neutrons can transform into an electron and a proton. when that happens in the nucleus, the proton stays in the nucleus while the electron shoots out at incredibly high speeds. that high speed electron is called a beta particle. the proton that stays is added to the other protons to increase the atomic number
What element is formed when Ra emits an alpha particle?
Next element in the periodic table ie Actinium.
When thorium emits beta particle the resulting nucleus has a atomic number?
The resulting element is protactinium, atomic number 91.
When thorium decays by emmitting an alpha particle what is the atomic number of the resulting nucleus?
88Ra, Radium
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
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.
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 is the atomic number of the resulting nucleus?
The proton count
If a radioactive nucleus with an atomic number of 88 emits an alpha particle what will the atomic number of the new nucleus be?
Two less, since the alpha particle takes away two protons.
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.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
alpha particle, He nucleus
