What else can I help you with?
How do you find the mass number without knowing the number of electrons?
The mass number doesn't depends on the number of electrons.
How do you tell the number of neutrons in an element?
Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.
Does the mass number equal the same number of electrons?
The atomic mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.
How do you find electrons?
you can find electrons by subtract the atomic number and atomic mass.
How many electrons and What is the atomic mass and number in chlorine?
17 electrons - atomic mass 35.5 and atomic number 17
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
Can you use the mass number of an element to determine the number of electrons in an atom?
No, the mass number of an element is the sum of protons and neutrons in the nucleus. To determine the number of electrons, you would need to know the atomic number of the element, which is equal to the number of protons. Electrons in a neutral atom equal the number of protons.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
How many electrons does and atom of tin have if its mass number is 118 and atomic number of 50?
Regardless of the mass number, a neutral element atom has electrons which is similar in number to the atomic number. Hence, an atom of the given element contains 50 electrons. Further, by considering the mass number, it can be concluded that there are 68 neutrons as the mass number is similar to the sum of protons and neutrons number of protons is equivalent to number of electrons.
How do you calculate the atomic mass number?
the atomic mass number is the number of protons/electrons in an atom
