How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
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.
Do valence electrons determine the atomic mass?
No, the valance electrons determine the charge, the atomic number is determined by the number of protons. Generally, electrons are equal to protons, but in ions it is different, so use protons.
What does the mass number in helium represent?
The mass number in helium represents the total number of protons and neutrons in the nucleus of a helium atom. It is used to determine the mass of the atom and differentiate between different isotopes of helium.
How many electrons are present in bromine atom with mass number of 87?
A bromine atom, regardless of its mass number, has an atomic number of 35, which means it has 35 protons and, in a neutral state, also 35 electrons. Therefore, a bromine atom with a mass number of 87 will have 35 electrons. The mass number indicates the total number of protons and neutrons, but it does not affect the number of electrons in a neutral atom.
Can the mass number of an element be used to determine the number of electrons in an atom?
No, the mass number of an element represents the total number of protons and neutrons in the nucleus, but it does not provide information about the number of electrons. The number of electrons in a neutral atom is equal to the number of protons in the nucleus.
Is it true that the mass number can be used to determine the number of electrons in an atom?
no --- atomic number
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
What determine the atom mass?
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
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.
What is counted in an atom to determine mass number?
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
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.
If a neutral atom has a mass of 12 amu and an atomic number of 5 determine the number of protons neutrons and electrons in the atom.?
Protons: 5 Neutrons: 7 Electrons: 5
What determine the mass and an atom?
Protons, neutrons and electrons
Do valence electrons determine the atomic mass?
No, the valance electrons determine the charge, the atomic number is determined by the number of protons. Generally, electrons are equal to protons, but in ions it is different, so use protons.
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.
