An atom of thorium loses 2 protons what element would be left?
Radium - 228.
What is The number of protons in an atom of an element is the element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
What is the kind of decay that results in the formation of a different element called?
Alpha 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 atomic nuclei.
What happens when the number of protons in an atom change?
The type of atom is now different from what it was. (It has a new identity.)
What do protons determine about an element?
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
An atom of thorium loses 2 protons what element would be left?
Radium - 228.
If an atom loses 2 protons what element would be left?
Well what element are you starting out with?
What is the number of protons and electrons in thorium?
Thorium's atomic number is 90. Thus, thorium has 90 protons per atom. To be electrically neutral then, thorium must also have 90 electrons per atom.
What is an atom called if it loses a proton?
the number of protons in an atom is what determines which element the atom is. So if an atom "lost" a proton, it would become another element entirely.
How many electrons are there in Thorium?
Thorium is a metal element. There are 90 electrons in a single atom.
Which element has 90 electrons as a neutral atom?
Thorium (Th).
Cations form when an atom gains electrons?
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
An ion is formed when am atom?
An ions is formed when an atom gains or loses electrons.
What is The number of protons in an atom of an element is the element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
If an atom loses an ion it has a charge of?
protons
Which element is an atom with six protons in the nucleus?
An atom with six protons in the nucleus is a carbon element.
An atom of an element contains 20 protons 20 neutrons and 20 electons This element is?
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.
