What element does thorium become if it emits an alpha particle?
The nuclear reaction is: 232Th--------------- 228Ra + α
When an alpha particle is emitted the nucleus of the original element?
An alpha particle is a helium-4 nucleus, and contains two protons and two neutrons. Therefore, the original nucleus will have two protons and two neutrons less. Its atomic number will be two less, and its atomic mass will be 4 less.
What part of an atom must change for the atom to become a new element?
An atom must gain or lose protons from its nucleus to become an atom of another element. The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.
When a neutron star is formed what particle is produced by the combining of the protons and electrons?
When a neutron star is formed, protons and electrons are crushed, they collide and become neutrons.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
The nucleus of the chemical element with atomic number 2 is known as an alpha particle. It is emitted by some radioactive substances during the process of alpha decay, where a parent nucleus releases an alpha particle to become a more stable daughter nucleus. Alpha particles consist of two protons and two neutrons bound together.
What happens if a particle has less protons than electrons?
The atom will become negatively charged (protons are positive and electrons are negative.)
How can an atom become positively or negatively charged by gaining or losing this subatomic particle?
An atom can become positively charged by losing an electron, resulting in more protons than electrons. Conversely, an atom can become negatively charged by gaining an electron, which creates an excess of electrons compared to protons.
What element does thorium become if it emits an alpha particle?
The nuclear reaction is: 232Th--------------- 228Ra + α
CAN An object becomes positively charged by gaining protons?
Yes, although the identity of the element changes (i.e. it will no longer by Hydrogen if you add a proton but it will be Helium.)
A neutral atom could become a positively charged particle through the loss of what?
A neutral atom could become a positively charged particle through the loss of one or more electrons. When an atom loses electrons, it becomes positively charged because there are more protons than electrons in the atom, creating an overall positive charge.
When an alpha particle is emitted the nucleus of the original element?
An alpha particle is a helium-4 nucleus, and contains two protons and two neutrons. Therefore, the original nucleus will have two protons and two neutrons less. Its atomic number will be two less, and its atomic mass will be 4 less.
When does a particle become charged?
gain or lose electrons
When do atomic nucleus charge grow?
When the atom gets bigger. Bigger atoms mean more protons in the nucleus. You can find out the number of protons by looking at a periodic table, it's the bottom number of each element. This is because the nucleus is positively charged (containing protons and neutrons) so the more protons there are, the more positively charged it will become.
What ion has 50 protons and 48 electrons?
The ion with 50 protons and 48 electrons is the element tin (Sn) with a charge of +2. This means it has lost two electrons to become positively charged.
What is the element that has the most protons of any element in group 18?
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
Changing the number of protons in an atom would change what?
If an atom were to change the number of protons it had than it would change the atomic number and therefore become a different element. Radioactive decay is one example of this, for example, alpha decay is when a radioactive nucleus emits an alpha particle (2 protons + 2 neutrons) and in doing so, becomes a nucleus of a different element. Polonium-212 decays to Lead-208 in this way.
When a atom gain or looses a valence electron it become a charged particle called an?
When an atom gains or looses a valence electron it becomes a charged particle called an ion
