no. elements are defined by their atomic number (the number of protons).
The key difference that causes atoms of one element to differ from all other elements is the number of protons in their nucleus. This number, known as the atomic number, determines the element's specific properties.
yes. Isotopes of an element have the same number of protons, thus electorns, thus the same chemical properties. Where isotpes differ is in the number of neutrons. Consider hydrogen, atomic number 1, atomic weight 1, 1 proton, 1 electron vs duterium, atomic number 1 atomic weight 2, 1 proton, 1 electron, 1 neutron. H2O = water D2O = heavy water
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.
Atoms of different elements differ in their number of protons, which determines the element's identity. Each element has a unique number of protons in its nucleus, leading to distinct chemical properties. Differences in the number of neutrons and electrons can result in isotopes and ions of the same element.
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
how do you find the atomic number for an element?
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
Atoms of the same element can differ from one another in their atomic mass, which is determined by the number of neutrons in the nucleus. These variations are called isotopes. Isotopes of the same element have the same number of protons but different numbers of neutrons.
Atomic number is the number of protons in the atoms of a particular element. Each element has its own unique atomic number.
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.
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
