They are called isotopes. Isotopes are atoms of the same element, and have the same atomic number (number of protons). However , they differ in the number of neutrons, so their atomic masses aren't the same. For example, chlorine has two stable isotopes, ³⁵Cl which makes up 76% and ³⁷Cl makes up 24%. ³⁶Cl is only a trace amount and is radioactive. The superscript in front of the chemical symbol is the mass number. The mass number is the sum of the protons and neutrons in the nucleus of the atom, in this case chlorine.
What else can I help you with?
What are different atoms of the same element that have different atomic masses?
These atoms are called isotopes and they have a different number of neutrons.
What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
What are atoms that have the same number but different weights?
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
What are atoms with same atomic mass but different atomic numbers called?
Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).
Atoms of the same atomic are called what?
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
Atoms that have the same atomic numbers but different atomic weights are called what?
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
What are atoms with the same atomic number but different mass called?
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
What are different atoms of the same element that have different atomic masses?
These atoms are called isotopes and they have a different number of neutrons.
Which refers to atoms with the same atomic number but different atomic masses?
They are called isotopes. eg we have different isotopes of carbon
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
What are atoms that have the same number of protons but different mass number?
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
Which number is the atomic number?
the number of protons in an atoms nucleus is called atomic number
What is it called when they have same atomic number but different mass?
They are called isotopes of the same element
What are atoms that have the same number but different weights?
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
What are isotopes and their differences?
Atoms of same element with same atomic number,which have different mass number is called isotops.
What is the number of protons in the nucleus of an atoms atomic?
The sum of protons and neutrons in the atomic nucleus is called "mass number"; this value is different for each isotope.
