When an element transmutates the number of changes?
protons
What element name symbol atomic number and ass number undergoes rusting?
Iron (symbol Fe, atomic number 26) is subject to corrosion.
Protactinium with 91 protons and a mass of 234 undergoes alpha decay and becomes what with an atomic number of what and an atomic mass of what?
It would be actinium with 89 protons and a mass of 230.
When an isotope undergoes beta decay which of the following does not change A the atomic number B the name of the element C the mass number D all of these change?
The mass number does not change.
When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
The answer is D. All of these change.
When an element transmutates the number of changes?
protons

If an isotope undergoes beta emission?
If a radioactive isotope undergoes beta emission, a. The atomic number changes B. the number of neutrons remains constant c. The mass number changes d. The todo isotope loses and electron
How many protons in uranium-235 atomic number 92 after undergoes fission?
93
Is an atomic number always equal to the number of protons?
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.
What is the atomic number of a thorium atom that forms when 238 92U undergoes alpha decay?
It is 90.
If astatine undergoes beta decay what element will result?
Atomic number becomes two units less and atomic mass four units less. Bismuth is the answer.
What happens to the mass number when it undergoes beta decay?
nothing, but another isotope with the same atomic mass is formed
Protactinium with 91 protons and a mass of 234 undergoes alpha decay and becomes what with an atomic number of what and an atomic mass of what?
It would be actinium with 89 protons and a mass of 230.
What happens to the atomic number of an atom undergoing alpha decay?
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.

The mass number does not change.
When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
The answer is D. All of these change.
