Translation for "massaluku" to english
Massaluku
Translation examples
Massaluku (tunnus A) on atomin ytimessä olevien nukleonien lukumäärä eli protonien ja neutronien lukumäärien summa.
The mass number of an element, A, is the number of nucleons (protons and neutrons) in the atomic nucleus.
Alfahajoamisessa atomin ytimestä poistuu alfahiukkanen, jonka jälkeen ytimen massaluku pienenee neljällä ja järjestysluku kahdella.
When an atom emits an alpha particle in alpha decay, the atom's mass number decreases by four due to the loss of the four nucleons in the alpha particle.
Kuten muilla lantanoideilla, useat isotoopeista ja etenkin sellaiset joiden massaluku on pariton, tai joissa on vähän neutroneja kuten 152Eu, voivat toimia neutronien sieppaajina.
Like other lanthanides, many isotopes, especially isotopes with odd mass numbers and neutron-poor isotopes like 152Eu, have high cross sections for neutron capture, often high enough to be neutron poisons.
