The atomic number is essential for the characteristics of a chemical element.

∙ 7y ago
it is unique for each element and distinguishes one element from another based on the number of protons in the nucleus. Just like how a fingerprint can identify a specific individual, the atomic number can identify a specific element in the Periodic Table.

What is the atomic number and similar elements of xenon?
The atomic number of xenon is 54. Xenon belongs to Group 18 of the periodic table, also known as the noble gases. Similar elements to xenon include krypton and radon.
Two isotopes of the same element have the same number of what?
Two isotopes of the same element have the same number of protons (atomic number). They differ in the number of neutrons in their nuclei, which gives them different atomic masses.
What is atomic number for HCl?
HCl does not have an atomic number because it is a compound made up of hydrogen and chlorine atoms. The atomic number for hydrogen is 1 and for chlorine it is 17.
Is golds atomic number 79?
mass number is simply the addition of the proton number and neutron number. we also know that proton number of the element is similar to atomic number. we also know that 79 + (197-79) is the no. of neutron no. of the gold. hence when atomic no. of the gold is 79 its atomic mass or mass number is 197.
What is atomic number of copper sulphate?
Copper sulfate does not have an atomic number because it is a compound made up of copper, sulfur, and oxygen atoms. The atomic number of copper is 29.
Is the number of neutrons equal to the atomic number?
In an atom, the number of protons is always similar to its atomic number. (The number of nutrons may be similar or different.)
How does the atomic mass relate to the atomic number?
These values are similar.
How are Magnesium atomic number 12 and Calcium atomic number 20 similar?
Both have two valence electrons had hence similar properties.
Why can you subtract the atomic number from the atomic mass and get the number of neutrons?
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
Why the relative atomic mass is not a whole number?
Bexause its similar with the atomic mass
What is the atomic number and similar elements of xenon?
The atomic number of xenon is 54. Xenon belongs to Group 18 of the periodic table, also known as the noble gases. Similar elements to xenon include krypton and radon.
What number of protons in a nucleus in an atom?
The number of protons is similar to the atomic number.
What number does the number of protons plus the number of neutrons give you?
The mass number (similar to the Atomic Mass and not to be confused with atomic number) When the number of protons and neutrons is added the result will be its atomic mass or mass number.
Why are the elements of the periodic table arranged in order of increasing atomic number?
The elements in the Periodic Table are arranged in order of increasing atomic number because it represents the number of protons in the atomic nucleus. It is the number of these protons, and their corresponding number of electrons, that determines the chemical properties of each element. It was found that when the elements lined up, the groups vertically had similar properties. They also increased by atomic mass. The table displays the patterns created by elements of similar properties.
