What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
What information could you use to determine the atomic number of unknown element that has a mass number of 22?
To determine the atomic number of an element with a mass number of 22, you would need the number of protons in the nucleus. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).
Which mass number or atomic number determine what element an atom is?
The identity of the element is determined solely by the atomic number, which is the number of protons.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
How can you determine the number of electrons in an element?
To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
If the atomic number of element D is 20 then what is the atomic number of element R?
34
How can one determine the number of electrons in an element?
To determine the number of electrons in an element, you can look at the element's atomic number on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
What is atomic number same as?
The atomic number is the same as the number of protons.
How do you determine neutrons in element?
subtract the atomic number from the mass number
Is the element determine by the number of protons?
The atomic number is equal to the number of protons.
Can you determine the element with only knowing the number of protons?
The number of protons is the "atomic number", so you look that up in the periodic table.
