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.
What else can I help you with?
How atomic number better than atomic mass?
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 what atomic number?
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.
Is the following true or false Two different elements can have the same 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.
Which two elements on a periodic table be reversed if you used atomic mass?
Tellurium (Te) and iodine (I) would be in reverse order if the elements were placed in order of atomic mass instead of atomic number.
What two factors determine the atomic mass of an elements?
neutrons and protons
How atomic number better than atomic mass?
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?
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 what atomic number?
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.
What is the atomic number of hydrogen chloride?
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.
What are the two ways that an elements symbol can be represented?
Atomic mass and Atomic number
What happens where two elements have the same 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.
Is the following true or false Two different elements can have the same 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.
Are all elements are compounds?
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.
Are all elements compounds?
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.
Can the atomic number be multiplied by two then equal the atomic mass?
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.
Do any two elements have the same atomic number?
no that's not possible
Are elements in a period arranged alphabetically?
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.
