What else can I help you with?
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
What subatomic particle is located inside the nucleus?
The centre of an atom is called the nucleus. The nucleus contains protons, which have a positive charge and neutrons which have no charge. Electrons are also subatomic particles but they go around the nucleus so they are not in the centre.
What isotope has 16 protons and 15 neutrons?
The isotope with 16 protons and 15 neutrons is oxygen-31.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
What is the number of protons neutrons and electrons of carbon 12?
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
Can not be considered a substance?
Energy, neutrons, electrons, and protons.
What is the name of the substance in which protons and neutrons are built?
ether
Does an atom have the same number of electrons protons and neutrons?
Sumtimes depends on the substance
How many neutrons do protons have?
Neutrons are completely separate from protons, so neutrons do not have any protons, and protons do not have any neutrons.
Elements must be what?
A pure substance made up of atoms, which contain protons, neutrons, and electrons.
How many protons are neutrons?
None -- all protons are protons, which are different from neutrons.
What is protons and neutrons of silicon?
14 protons and 14 neutrons
How are neutrons and protons different?
Protons are positively charged and neutrons are neutral.
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
What sub-atomic particles are found in the nucleus?
Protons and neutrons; protons and neutrons contain quarks and gluons.
How many protons neutrons are in iridium 192?
77 protons, 115 neutrons.
Can atoms be broken down into smaller particles if Yes then what are the names of the particle?
