What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
Which is not unique to each element?
Although the number of protons in the nuclei of the atoms of an element is constant, the number of neutrons varies in general. For instance, hydrogen comes in three forms, known as isotopes, one with no neutrons in its nucleus, one with one neutron and one isotope with two neutrons in its nucleus.
What are atoms of the same element that only differ in the number of neutrons known as?
Isotopes.For instance, Carbon by convention has 12 components to it's nucleus (6 protons with a positive charge, and 6 neutrons without any charge) but carbon compounds also contain a radioactive isotope called carbon 14 which has an additional 2 Neutrons. Carbon 14 percentages is what is used in radiometric dating (carbon dating) to give some idea how old a specimen might be.
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
Is The number of protons plus the number of neutrons in the nucleus of an atom known as the mass number?
Yes, the sum of protons and neutrons in the nucleus of an atom is known as the mass number. The mass number is used to identify different isotopes of an element.
Forms of the same element that differ in number of neutrons?
such forms of an elements are known as isotopes.
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.
Atoms of the same element that differ in the number of neutrons they contain are known as?
they are known as isotopes. Dont ask people to do your homework
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
In what properties do atoms of different elements differ from each other?
Atons are distinguished by the number of protons in their nucleus. The number of neutrons in an element can vary depending on what isotope it is; the number of electrons can vary to make ions of differing charges.
What are atoms element that have a different number of neutrons known as?
Isotopes
True or false- all atoms of the same element have the same atomic number?
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
Why doesn't the number of neutrons identify an element?
The number of neutrons in an atom does not identify the element because different isotopes of an element can have the same number of protons (which determines the element) but varying numbers of neutrons. Isotopes of an element have the same number of protons, but differing numbers of neutrons.
What element is the number of protons and neutrons in the nucleus?
All elements have neutrons and protons within the nucleus.
What are atoms that are of the same element having same number of protons but different number of neutrons known as?
isotopes
When an element have different atomic number and the same mass number what is it called?
Do you mean same atomic number and different mass numbers? If so then these are known as ISOTOPES. All atoms of any given element will have the same atomic number (number of protons in the nucleus) as this is what makes the element what it is. It is the number of neutrons in the nucleus which varies and hence the mass number (the number of protons plus the number of neutrons). For eg Carbon has three ISOTOPES - carbon-12, carbon-13 and carbon-14. They all have atomic number of 6 (6 protons in their nucleii) but have different numbers of neutrons (6, 7 or 8 respectively) and therefore different mass numbers.
