How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
What element has a mass number of 56 with 36 neutrons?
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.
What is the relationship between mass number and atomic numbers?
Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
The mass of any two atoms of the same element is always the same?
The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
What tells you how many atoms of an element there are?
the atomic mass, which is the mass of its protons and neutrons and electrons together
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
How are atomic number and atomic mass alike?
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
What does it mean when the neutrons of an atom are all different?
The number of neutrons present in atoms of an element may differ. Atoms of an element which have different numbers of neutrons are called isotopes. These differ in mass but have the same chemistry.All of the neutrons in the nucleus of an atom are the same.
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
Which element has a different number of neutrons?
Isotopes are different atoms of the same element with a different atomic mass. This difference is caused by a different number of neutrons.
Atoms of the same element that have a different number of neutrons and a different atomic mass are what?
isotopes
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
12343 neutrons
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the term for atoms of two atoms of the same element with different molecular mass?
They are called isotopes. They differ in molecular mass due to the different number of neutrons.
Atoms of the same elements that differ only in the number of neutrons are known as?
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.
