Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
What make an atom an isotope?
When an atom of an element has a different number of neutrons.
Do atoms have equal electrons and protons?
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
What are atoms that have the same element but different neutrons?
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
What part of an atom must change for the atom to become a new element?
An atom must gain or lose protons from its nucleus to become an atom of another element. The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
A chlorine atom with 18 neutrons is what element?
A chlorine atoms is always a molecule of chlorine, irrespective of the number of neutrons it may have.
If there was an atom of this element that has 18 neutrons would it still be the same element?
Yes. Atoms with a different number of neutrons are called isotopes of that atom, but a variation in the number of neutrons does not change what the atom is.
How many neutrons does Krytpon-82 have?
The answer to how many neutrons an atom of an isotope has is always the difference between the mass number of the isotope and the atomic number of the element. The atomic number of krypton is 36. Therefore, an atom of krypton-82 has 46 neutrons.
Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
Any element can always be identified by its?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
What is the neutron and proton responsible for in an atom?
Protons make up the identity of the element and give it its unique properties. Protons have a positive charge. Neutrons give an atom additional mass, and the number of neutrons in an atom make it an isotope of an element. Neutrons have no charge.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What make an atom an isotope?
When an atom of an element has a different number of neutrons.
Atom of an element with different number of neutrons?
Isotope
How many neutrons are in the nucleus of an atom with an atomic number of 25?
The number of neutrons in the nucleus of an atom varies for each isotope of the element. Atomic number 25 means the atom contains 25 Protons, and it is the element Manganese (Mn). Manganese has 4 isotopes 52Mn, 53Mn, 54Mn & 55Mn. Take the number of protons (always 25 with Mn) from the isotope number and you will have the number of Neutrons in the nucleus. eg 55Mn will have 30 Neutrons.
Will an atom with more neutrons react identically to an atom of the same element with fewer neutrons?
Not always. Some atoms of the same element with different numbers of neutrons are radioactive, whereas the other atoms are not.
