How is the mass number of an element affected when it decays by ejecting an alpha partical?
The mass number of an element decreases by 4 when it decays by ejecting an alpha particle. This is because an alpha particle has a mass number of 4 and atomic number of 2. The atomic number of the element also decreases by 2.
What is the change in an mass number after alpha decay?
The mass number decreases by 4 and the atomic number decreases by 2 after alpha decay. This is because an alpha particle consists of 2 protons and 2 neutrons, which are emitted during the decay process.
How Are the atomic and mass number Affected by positron emission?
During positron emission, a proton in an unstable nucleus is transformed into a neutron, resulting in the emission of a positron (the antimatter counterpart of an electron). This process decreases the atomic number (Z) by one, as the number of protons decreases, but the mass number (A) remains unchanged since the total number of nucleons (protons and neutrons) is unaffected. Consequently, the element transforms into a different element that is one position to the left on the periodic table.
What happens to the atomic number when an alpha particle is given off?
Alpha emission in an atom reduces its atomic number by two. A link can be found below to the related question about what alpha decay is.
What is the term for the value that indicates the number of protons for an atom of a given element?
The atomic number is the number of protons in an atom of an element.

How can you use the parent element to determine the daughter element in alpha decay?
In alpha decay, the parent element (nucleus) emits an alpha particle consisting of 2 protons and 2 neutrons. The daughter element is formed by subtracting the alpha particle from the parent element's atomic number and mass number. The daughter element is often located two positions to the left on the periodic table compared to the parent element.
What is the term for the value that indicates the number of protons for an atom of a given element?
The atomic number is the number of protons in an atom of an element.
What does the atomic number of an element tell you about the element?
Atomic number = Number of protons
What is the atomic number of the element with the symbol Be?
The atomic number of the element with the symbol Be (Beryllium) is 4.
What is the element argon atomic number?
Argon is a gas element. atomic number of it is 18.
What does an element's atomic number stand for?
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
Which element has the highest atomic number?
The element with the highest atomic number is Oganesson, with the atomic number 118.
What is the element of a atomic number element?
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.
