When an element transmutates, its number of protons change, which in turn changes its atomic number and chemical properties. These changes can result in the formation of a different element with different physical and chemical characteristics.
Iron (symbol Fe, atomic number 26) is subject to corrosion.
When Fr-223 undergoes alpha decay, it emits an alpha particle consisting of two protons and two neutrons. This transforms the nucleus into a different element with atomic number decreased by 2 and atomic mass number decreased by 4.
It would be actinium with 89 protons and a mass of 230.
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.

Yes, it is. The type of atom is defined by the atomic number. Usually, when an atom undergoes a chemical reaction, only the sharing/possession of electrons changes, and the number of protons (and so the atomic number of the element) stays the same. When an atom somehow undergoes a nuclear reaction, which is possible, the number of protons sometimes do change, but in that case the atomic number (and thus the element type) becomes different as well.
If an isotope undergoes beta emission, a neutron in the nucleus is transformed into a proton, along with the emission of a beta particle (an electron) and an antineutrino. This process increases the atomic number of the nucleus by one but leaves the mass number unchanged.
It is 90.

nothing, but another isotope with the same atomic mass is formed
The atomic number of an atom undergoing alpha decay decreases by 2. Not asked, but answered for completeness, the atomic mass number decreases by 4.
It would be actinium with 89 protons and a mass of 230.
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.
Atomic number becomes two units less and atomic mass four units less. Bismuth is the answer.
When thorium-234 undergoes beta decay, a neutron in the nucleus is converted into a proton, resulting in the formation of protactinium-234, with atomic number 91.
