An isotope of iron has 26 protons and 32 neutrons what is the mass number?
An unknown element contains 24 protons, 21 electrons,and has mass number 54
How many neutrons are present in a magnesium atom with a mass number of 24?
A magnesium atom with a mass number of 24 has 12 protons because the atomic number of magnesium is 12. To find the number of neutrons, you subtract the atomic number from the mass number: 24 (mass number) - 12 (atomic number) = 12 neutrons.
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
What is the mass number for Mg?
Magnesium is a metal element. Mass number of it is 24.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
What is the mass number of a magnesium atom with 14 neutrons?
The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass number).
In a magnesium atom where are the protons and neutrons?
In an atom protons and neutrons are located in the atomic nucleus.
The most stable isotope of an atom with 12 protons probably has neutrons?
Mass of protons + Mass of neutrons + mass or electrons - Binding energy of the atom. Do not forget to subtract the binding energy. If you teacher never mentioned this, then he/she is wrong. You always have to subtract the binding energy to find the real mass.
What are the protons neutrons and electrons for magnesium atom?
Atomic # : 12 Mass Number : 24 # of Protons : 12 #of Neutrons : 12 # of Electrons : 12
What element has 12 electrons and 12 protons and 14 neutrons?
This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
Magnesium protons and electrons?
A magnesium atom has 12 protons, 12 electrons, and 12 neutrons. Protons carry a positive charge, electrons a negative charge, and neutrons have no charge. The number of protons determines the element (in this case, magnesium), while the number of electrons balances the positive charge of the protons to maintain a neutral atom.
How many neutrons and protons are in Magnesium 26?
Manesium 24 has 12 electrons, protons and neutrons.
How many neutrons are in a atom of magnesium?
A magnesium atom typically has 12 neutrons. Magnesium has an atomic number of 12, indicating it has 12 protons which is equal to its number of electrons in a neutral atom. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of magnesium, which is approximately 24.305 amu.
Is an atom with 12 protons 12 neutrons and 12 electrons an isotope?
No, an atom with 12 protons, 12 neutrons, and 12 electrons is not an isotope. Isotopes are atoms of the same element with different numbers of neutrons. Since this atom has the same number of protons, neutrons, and electrons, it is a stable and neutral atom of magnesium.
How many protons and neutrons are in Mg?
The number of protons (p+) in the nuclei of an element's atoms is the atomic number of the element. In this case, the atomic number of magnesium is 12. In a neutral atom, the number of electrons (e-) equals the number of protons. So all neutral magnesium atoms have 12 protons and 12 electrons. Isotopes of an element differ in the number of neutrons (n0).There are three stable isotopes of magnesium (Mg) identified by their mass numbers; magnesium-24, magnesium-25, and magnesium-26. The mass number is the sum of protons and neutrons in the nucleus of an atom. To determine the number of neutrons, subtract the atomic number from the mass number. (mass number - atomic number = no. of neutrons)Magnesium-24: 24 - 12 = 12; An atom of Mg-24 has 12 p+, 12 e-, and 12 n0.Magnesium-25: 25 - 12 = 13; An atom of Mg-25 has 12 p+, 12 e-, and 13 n0.Magnesium-26: 26 - 12 = 14; An atom of Mg-26 has 12 p+, 12 e-, and 14 n0.
An isotope of iron has 26 protons and 32 neutrons what is the mass number?
An unknown element contains 24 protons, 21 electrons,and has mass number 54
What element has 12 protons and 10 neutrons?
Any atom, ion, or isotope with 12 protons is going to be magnesium. Only the number of protons in the nucleus will determine the element. But with the information about the number of neutrons, the specific isotope can also be determined - 22Mg.
