Isotope
Isotopes.
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
The Proton number defines the element, so there cannot be two atoms of the same element with different proton numbers, because they will be, by definition, different elements. Neutron numbers can differ though. When one element has different neutron configurations, these are called Isotopes.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
Is called an Isotope.
An element has a small case in the center called the nucleus. Inside the nucleus contains protons an nuetrons. Protons have a positive charge and nuetrons have a negative charge. On the outside and are energy levels that have electrons and are negatively charged
mass number = protons + nuetrons
Not isomers, Isotopes
Hydrogen only has one proton. A Hydrogen-3 atom contains one proton and 2 nuetrons. This is because atoms of a certain element can vary in the amount of nuetrons. The're called isotopes.
They are called isotopes.
They are called isotopes.
They are isotopes of that element, they have different neutron numbers.
It's called an isotope.
nuetrons
the short and notation of an element is called as symbol. the short and notation of a compound is called as formula.
