All the elements have an atomic number. The atomic number is the number of protons found in the atom of a certain element. And to equalize themselves the atoms will usually have the same amount of electrons as protons so electrons also equal the atomic number. The atomic number is the number on the top of the box on the periodic table for each element. You must have been asking what two subatomic particles make up the atomic number. In that case it would be the proton and the electron because the neutron is so mall that chemist's usually nullify it.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
No two elements will have the same atomic number because the atomic number of an element is determined by the number of protons in the nucleus of an atom. Since each element has a unique number of protons, each element will have a unique atomic number.
False. The atomic number of an element is defined by the number of protons in its nucleus, which is unique to each element. Therefore, two different elements cannot have the same atomic number.
Tellurium (Te) and iodine (I) would be in reverse order if the elements were placed in order of atomic mass instead of atomic number.
neutrons and protons
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.
No two elements will have the same atomic number because the atomic number of an element is determined by the number of protons in the nucleus of an atom. Since each element has a unique number of protons, each element will have a unique atomic number.
Since hydrogen chloride is not an element but is, instead, formed by two elements, it does not have an atomic number. Only elements have atomic numbers.
Atomic mass and Atomic number
When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.
False. The atomic number of an element is defined by the number of protons in its nucleus, which is unique to each element. Therefore, two different elements cannot have the same atomic number.
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
Not generally. For light elements this relation is often approximately true, but for heavier elements, the gram atomic mass is more than two times the atomic number, as the ratio of neutrons to protons increases with increasing atomic mass.
no that's not possible
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
