Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
As all the other chemical elements bohrium contain protons, neutrons and electrons.
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
Protons and Electrons
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
helium
The chemical element with 20 protons and 20 neutrons is Calcium(Ca). The number of protons is equal to the number of electrons, and the number of electrons is equal to the atomic number.
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
Boron is an atom or element, and it contains protons, electrons, and neutrons.
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons) R
Manganese has 25 protons, 25 electrons and 30 neutrons.
Protons, Neutrons, and Electrons
As all the other chemical elements bohrium contain protons, neutrons and electrons.
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
Nickel (Ni) is a chemical element with the chemical symbol Ni and atomic number 28. Nickel has: protons=28 neutrons=30 electrons=28 atomic mass=58 atomic #=28
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
Protons and Electrons
...electrons.Isotopes contain the same number of protons (hence, the same number of electrons) and electrons are what determine reactivity. 2nd answer : The isotopes have the same chemical properties because the electronic configuration of an element is same there fore isotopes posses the same chemical properties .
