Atomic number becomes two units less and Atomic Mass four units less.
Bismuth is the answer.

What kind of decay results in the formation of a different element?
both top and bottomAlpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its nuclei.or to be more blunt without all the detail radioactive
What is a parent and daughter element?
In chemistry, a parent element is a radioactive element that undergoes decay to form a different element known as the daughter element. The parent element gives rise to the daughter element as a result of radioactive decay processes such as alpha decay, beta decay, or electron capture. The daughter element has a different number of protons and atomic number compared to the parent element.
What is the half life of astatine?
Astatine has many isotopes, each with its own half life. The longest in my list is At209 at 8.1 hours, and At215 is listed at 0.1 ms. The shortest are just listed as 'short' reflecting the small quantities.
What does it mean for an isotpe to be radioactive?
An isotope is radioactive if it undergoes spontaneous decay, emitting particles or radiation in the process. This decay results in the transformation of the atomic nucleus into a different element or a different isotope of the same element.
Alpha decay and beta decay are two forms of decay that cause transmutation?
Transmutation, which is the change of atoms from one element to another.
When the nuclide astatine-218 undergoes alpha decay?
When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.
What is the 85th element on the Periodic Table of Elements?
The 85th element on the Periodic Table of Elements is astatine (At). It is a highly radioactive element and the heaviest known halogen. Astatine is rare and is primarily produced as a result of decay processes in uranium ores.
When an element undergoes nuclear transmutation the result is a completely different what?
When an element undergoes nuclear transmutation the result is a completely different element or isotope. All transmutation occurs through decay or nuclear reaction.
If seaborgium undergoes alpha decay which element is created?
If seaborgium undergoes alpha decay, it would create rutherfordium as the resulting element.
What is a radioactive nonmetal At Po Ra Xe none of these?
Astatine is a radioactive, natural element and also a nonmetal similar to halogens.
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
What is the lightest element that can undergo radioactive decay and what type of decay occurs in that element?
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
How many isotopes does the element astatine from the periodic table have?
Astatine, a radioactive element found in the halogen group, has at least 20 known isotopes. However, only one of these isotopes, Astatine-210, is considered stable. The other isotopes are unstable and undergo radioactive decay.
What happens to a radioisotope when it undergoes decay?
This isotope is transformed in another isotope of another element.
Is astatine found as a pure element in nature or in a compound?
Astatine is found naturally as a member of the radioactive decay series: uranium, thorium and actinium series; the chemical form is not excatly known.
Can an element of the periodic table be changed but not by combining another element?
It is possible if the element undergoes nuclear decay. But this is possible only for unstable isotopes.
Does astatine rust?
Well, hello there! Astatine is a very rare and highly reactive element, so it can react with other elements in the environment. However, astatine is not known to rust like iron does. Instead, it tends to undergo radioactive decay relatively quickly. Just remember, every element has its own unique way of interacting with the world around it.
