Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
What else can I help you with?
What was Formerly element atomic number 41 now called niobium?
molybdenum. a black powder as used in oil additive like sulphide.
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.
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
Each element has been assigned a number what is it called?
The numbering arrangement of elements is called the atomic number. Atomic number determines the number of protons in an element's nucleus and defines its unique chemical properties.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.
The various atomic weights of the same element are called what?
Isotopes
Are atons of an element having the same atomic no but different atomic weights?
Yes, and they are called isotopes.
The various atomic masses of the same element 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 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 was Formerly element atomic number 41 now called niobium?
molybdenum. a black powder as used in oil additive like sulphide.
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 element has a relative atomic mass of 15.5?
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
The number of protons in the nucleus of an element is called?
the answer is that it is called a atomic number.
What is the number in front of an element called?
atomic number
