Mass is irrelevant when determining the number of PROTONS. The atomic number is the number of PROTONS so the answer is 19. Mass is approximately number of PROTONS plus the number of NEUTRONS. ELECTRONS mass is so small compared to protons and neutrons that they are usually ignored.

What is the atomic number of an atom contains 40 protons 40 electrons and 51 neutrons?
The atomic number is the number of protons in the nucleus which, for a neutral atom, would be 32.
The number of protons in an atom of an element?
It is equal to the no. of electrons in the atom. It is called the atomic number.
Can an atomic number tell you how many protons an atom has?
The atomic number is the number of protons in an atom's nucleus.
What is number of positively charged protons in an atom's nucleus is the?
the number of protons in a single atom depends on the element. for example, hydrogen would have 1, helium would have 2, beryllium would have 3, and so on. the number of protons in a single atom depends on the element. for example, hydrogen would have 1, helium would have 2, beryllium would have 3, and so on.
Atomic number equals the number of?
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
How would you describe the atomic number?
Atomic number is about protons. It symbolises the protons an atom has.

A sub atomic particle which determines the atomic number?
The atomic number of an element is equal to the number of protons in the nucleus of that element.
The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
Number of protons in a an atom of an atom?
The number of protons in an atom is its atomic number.
What is the atomic number of an atom determained by the number of what?
The atomic number of an atom is determined by the number of protons it has.
How many protons does an atom have if its atomic number is 4?
The atomic number IS the number of protons in the atom's nucleus.
Can an atomic number tell you how many protons an atom has?
The atomic number is the number of protons in an atom's nucleus.
How is an atoms atomic number related to it's number of protons to electrons?
The atomic number of an atom is the number of protons in the nucleus of that atom. The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons. The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.
