When an atomundergoesalpha decay, it loses two neutrons (as well as two protons).
The mass does not change much. The Atomic number will increase though.
No, in alpha decay the atomic number of the daughter nucleus is decreased by 2 and the mass number is decreased by 4 compared to the isotope undergoing decay. This is because an alpha particle (helium nucleus) is emitted during alpha decay, resulting in a new daughter nucleus with a lower atomic and mass number.
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
Alpha decay is the emission of an alpha particle, which consists of two protons and two neutrons. During alpha decay, the parent nucleus loses an alpha particle to become a different nucleus called the daughter product. The daughter product formed after alpha decay will have an atomic number that is two less and a mass number that is four less than the parent nucleus.
Alpha decay involves the emission of an alpha particle (helium nucleus) from the nucleus. This reduces the atomic number by 2 and the mass number by 4, creating a new element. The nucleus becomes more stable due to the reduction in excess nuclear energy.

Alpha decay has the greatest mass, as it involves the emission of an alpha particle consisting of two protons and two neutrons. This particle has a mass of around 4 atomic mass units.
There are three main types of radioactive decay: alpha decay, beta decay, and gamma decay. Alpha decay involves the emission of an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. This type of decay reduces the atomic number of the nucleus by 2 and the mass number by 4. Beta decay involves the emission of a beta particle, which can be either an electron (beta-minus decay) or a positron (beta-plus decay). Beta decay changes the atomic number of the nucleus by 1 but does not significantly affect the mass number. Gamma decay involves the emission of gamma rays, which are high-energy photons. Gamma decay does not change the atomic number or mass number of the nucleus but helps the nucleus reach a more stable energy state. These types of decay differ in the particles emitted and the changes they cause to the nucleus.
If Sulfur-34 undergoes alpha decay, it will become silicon-30. This is because in alpha decay, the parent nucleus loses an alpha particle (which is a helium nucleus composed of 2 protons and 2 neutrons), resulting in a new nucleus with an atomic number reduced by 2 and a mass number reduced by 4.
Transmutation, which is the change of atoms from one element to another.
Alpha decay is the emission of an alpha particle, which consists of two protons and two neutrons. During alpha decay, the parent nucleus loses an alpha particle to become a different nucleus called the daughter product. The daughter product formed after alpha decay will have an atomic number that is two less and a mass number that is four less than the parent nucleus.
The mass number of a nucleus decreases during nuclear reactions involving alpha decay, beta decay, and neutron emission. In these reactions, the nucleus loses mass as particles are emitted, resulting in a decrease in the mass number.
The greatest mass loss to a nucleus undergoing decay by emission happens through alpha radiation. In this case, the atomic mass is reduced by approximately 4. Emission of a neutron (rare) or proton produces a loss of about 1. Other emissions cause smaller losses.
Alpha decay involves the emission of an alpha particle (helium nucleus) from the nucleus. This reduces the atomic number by 2 and the mass number by 4, creating a new element. The nucleus becomes more stable due to the reduction in excess nuclear energy.
