No. of neutrons= Mass no.- No.of protons(atomic no)
therefore, no. of neutrons =96-42
= 54

Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
An atom of carbon whose mass number is 14 differs from an atom of carbon whose mass number is 12 in that it has?
neutrons, subtract the atomic number from the mass number to find the number of neutrons, atomic number is the number is the amount of protons, atomic mass is the average mass of one mole of atoms. each particle wieghing one amu (atomic mass unit)
How many protons neutrons and electrons in 58cr and 63cr?
Assuming that the questioner intended to write "Cr" instead of "cr", the isotopes indicated are those of the element chromium, whose atomic symbol is "Cr" and whose atomic number is 24. The atomic number is defined as the number of protons in a nucleus of each atom, and the atomic mass number, which precedes the atomic symbol, is defined as the number of protons and neutrons combined. In order to maintain electrical neutrality as is required for any atom, the number of electrons must be the same as the number of protons. From the definition of mass number, it follows that the number of neutrons is equal to the atomic mass number minus the atomic number. Therefore, each isotope named in the question has 24 protons and 24 electrons, but the isotope with mass number 58 has 32 neutrons and the isotope with mass number 63 has 32 neutrons has 39 neutrons.
What is the atomic number of an element whose atoms have 9 protons and 10 neutrons?
The atomic number is the number of protons. It is also the number of electrons. The atomic mass equals the protons and neutrons together/weight of the nucleus. So, the atomic number would be nine, because there are 9 protons. The atomic mass would be around 19, because there would be 9 protons and 10 neutrons in the nucleus. The element you are talking about is actually Fluorine, and on the periodic table it says that the atomic mass is 18.9984032. This is because the atomic mass is usually never an exact amount. You can round this decimal place to 19, anyway.
The atomic weight of an element whose atoms contain 8 protons 8 electrons and 8 neutrons is?
That would be an oxygen isotope and it's Atomic Mass would be 16. (Protons + Neutrons) The mass of an electron is so minuscule that it is not even factored into the mass.
Isotopes are atoms whose nuclei have the same atomic number bith with different number of?
Neutrons

Calculate the number of protons of the atom whose mass number is 19 and whose number of neutrons is 10?
Mass number 19 means a total of 19 protons and neutrons. If it has 10 neutrons, that leaves 9 protons, which is Fluorine.

The atomic mass of an element whose atoms consist of eight protons nine neutrons and eight electrons is what?
To calculate atomic mass, only the amount of protons and neutrons will be summed. So eight protons plus nine electrons equals seventeen atomic mass units.

How do you work out how many electrons protons and neutrons an atom has?
if it is a discovered element, look up its atomic number. that is a count of the number of protons in an atom of that element. the number of protons can also be determined by the magnetic charge with no electrons.
How many neutrons are in seaborgium?
Seaborgium (106Sg) is a synthetic element whose most stable isotope 271Sg has a half-life of 1.9 minutes. Number of neutrons in Sg-271 is 271-106= 165 neutronsA new isotope 269Sg has a potentially slightly longer half-life (ca. 2.1 min) based on the observation of a single decay. This one (Sg-269) has 269-106= 163 neutrons
What atom of an element with a different number of neutrons?
Isotopes.
What two element's atomic numbers multiply to be 45?
Fluorine (whose atomic number is 9) and Boron (whose atomic number is 5).
