The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
oh actually i know the answer
31 daltons.
The atomic nucleus contain neutrons and protons.
The atomic nucleus contains protons (at least one) and zero or more neutrons.
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
Physicists believe that there is a cluster of Protons and Neutrons within an Atom's nucleus.
Protons and neutrons are in the center of an atom in the nucleus. Electrons are dispersed around the nucleus.
The atomic nucleus contain neutrons and protons.
The atomic nucleus contains protons (at least one) and zero or more neutrons.
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
No, the nucleus contains protons and neutrons. Electrons are outside of the nucleus.
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
Protons and neutrons are normally found in the atomic nucleus.
This is the atomic nucleus.
This is the atomic nucleus.
The atomic nucleus contain protons and neutrons.
Protons and neutrons are situated in the atomic nucleus; electrons surround the nucleus, arranged in shells.
nucleus does not have noble gases. nucleus contains sub atomic particles like neutrons and protons.
The nucleus of an atom carries a positive charge, as this is where protons are located.
