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.
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.
By how many units do that atomic numbers of these two elements differ?
To determine how many units the atomic numbers of two elements differ, you need to know the atomic numbers of both elements. The atomic number is defined as the number of protons in an atom's nucleus. Once you have the atomic numbers, you can simply subtract one from the other to find the difference in units. If you provide the names or symbols of the two elements, I can give you the specific difference.
Can elements be ordered by there atomic number?
Yes, elements can be ordered by their atomic number. The atomic number of an element corresponds to the number of protons in an atom's nucleus, and elements are arranged in the periodic table from lowest to highest atomic number.
What two elements whose atomic mass order does not match their atomic number order?
The two elements that exhibit a discrepancy between atomic mass order and atomic number order are potassium (K) and argon (Ar). Potassium has an atomic number of 19 and an atomic mass of about 39.1, while argon has an atomic number of 18 and an atomic mass of approximately 39.9. This means that argon, which is lighter in terms of atomic mass, appears after potassium in the periodic table based on atomic number.
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.
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
By how many units do that atomic numbers of these two elements differ?
To determine how many units the atomic numbers of two elements differ, you need to know the atomic numbers of both elements.

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.
