Atom of element X has mass 5 times than that of Carbon-12 What is its atomic mass?
Willisj1981
Mass of Carbon-12 = 12 amu
5times of mass of Carbon-12 atom = 5 x 12 = 60 amu
So Atomic Mass of element X = 60 amu

The number of electrons in an atom of an element is the same as the element's?
The number of electrons in an atom of an element is the same as the element's atomic number. The atomic number is the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.
What is the atomic number of in atom?
The atomic number of an atom is equal to the number of protons in its nucleus. It determines the element's identity on the periodic table.
What is the atomic number of an atom or element?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number is unique for each element and positions the element in the Periodic Table.
Why is the atomic mass scale also called the relative atomic mass scale?
The atomic mass scale is sometimes referred to as the relative atomic mass scale because it is a scale that compares the mass of atoms of different elements to the mass of a carbon-12 atom, which is assigned a mass of exactly 12 atomic mass units. By comparing the masses of atoms relative to carbon-12, scientists can determine the relative masses of different elements.
What is the atomic number of an element?
The atomic number of an element is the number of protons in the nucleus of its atom. It is represented by the symbol Z in the periodic table. The atomic number determines the identity of the element and its unique properties.
What are the atomic numbers and atomic mass?
Atomic Number :- atomic number of an element is the number of protons present in the nucleus of the atom. (since atoms are electrically neutral the number of protons in an atom is equal to the number of electrons in an atom) Atomic Mass :- atomic mass of an element is the number which tells us how many times an atom of that element is heavier than an atom of hydrogen (whose atomic weight is taken as unity [1])
An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
The number of protons in an atom of an element?
The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.
The number of electrons in an atom of an element is the same as the element's?
The number of electrons in an atom of an element is the same as the element's atomic number. The atomic number is the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.
What is the atomic number of an atom element?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number is unique for each element and positions the element in the Periodic Table.
What does the atomic mass tell you about the atom?
The Atomic Mass of an element tells you the average mass of an atom in the element.
The atomic number of an element indicates the number of .. in an atom?
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
What number of protons in one atom of an element is that element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
Is it true that every atom of the same element has the same atomic number?
Yes. It is true. An atom with a different atomic number is an atom of a different element.
How does an atom get its atomic number?
An atom's atomic number is the number of protons within the single atom of an element
What is the atomic number of an atom or element?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number is unique for each element and positions the element in the Periodic Table.
Why is the atomic mass scale also called the relative atomic mass scale?
The atomic mass scale is sometimes referred to as the relative atomic mass scale because it is a scale that compares the mass of atoms of different elements to the mass of a carbon-12 atom, which is assigned a mass of exactly 12 atomic mass units. By comparing the masses of atoms relative to carbon-12, scientists can determine the relative masses of different elements.
