The atomic number by definition is the number of protons in the nucleus, therefore 19 in this instance. (The isotope effectively specified by the numbers given in the question is potassium-40, which is least commonly occurring natural isotope of potassium.)

Does the nucleus contain neutrons and electrons?
No, the nucleus contains protons and neutrons. Electrons are outside of the nucleus.
What is the composition of the atom and how the subatomic particles are arranged?
Protons and neutrons are situated in the atomic nucleus; electrons surround the nucleus, arranged in shells.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
What describes the bohr atomic model?
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
Is it correct that nucleus contains electrons and protons?
The atomic nucleus contain neutrons and protons.
How many protons neutrons and electrons are in a neutral atom of 64Cu atomic number 29?
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
Does the nucleus contain neutrons and electrons?
No, the nucleus contains protons and neutrons. Electrons are outside of the nucleus.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
How many protons neutrons and electrons in carbon-14?
Carbon 14 has 6 protons, 8 neutrons, and (in the neutral atom) 6 electrons.
Protons electrons and neutrons are the three main parts of these?
Protons, electrons, and neutrons are the three main parts of atoms. In an atom, the nucleus contains the protons and neutrons, the electrons are found in shells around the nucleus. On the periodic table, the atomic number tells you the number of protons of an element.
Atomic particles located in the nucleus?
Neutrons and protons.
How many protons electron and neutrons are in nitrogen?
A neutral nitrogen atom has 7 protons, 7 neutrons, and 7 electrons. If it is electrically charged, the number of electrons will be different. If it is an isotope of nitrogen other than the most common (N-14), the number of neutrons will be different. Protons = Atomic Number Neutrons = Atomic Mass - Protons Electrons = Protons Atomic number is the amount of protons in element.
How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
How many protons neutrons electrons atomic number and atomic mass does bromine have?
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
