Atomic Number identifies the following:
- No. of protons (same as the atomic number)
- No. of electrons (mostly same as no. of protons)
- Approximate Atomic Mass (No. of neutrons are roughly equal to or near to no. of protons)
What else can I help you with?
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
Boron has an atomic mass of 11 and an atomic number of 5 so the number of neutrons must be?
The number of neutrons in an atom is calculated by subtracting the atomic number from the atomic mass. In this case, for boron with an atomic mass of 11 and atomic number of 5, the number of neutrons would be 6.
What two elements make up the atomic number?
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.
Sodium has an atomic mass of 23 and an atomic number of 11 so the number of neutrons must be?
Sodium does have an atomic number of 11, and if the isotope's atomic mass is 23, the atom would have 11 protons (the atomic number) and 12 neutrons (the atomic mass minus the atomic number). The atom would have 11 electrons, and when ionized it would lose one and take on a charge of +1.
A neutral atom with an atomic number 92 must have?
This atom is uranium; 92 protons, 92 electrons and a variable number of neutrons depending on the isotope.
What element has an atomic number that is double the atomic number of silicon?
Chromium atomic number is 24 and silicon atomic number is 14 so double of 14 is 28 so it must be nickel. i am not sure but it must be that
If there is a difference between a substance atomic number and its atomic mass which measure must be the larger number?
The atomic mass number must be higher as that represent the number of protons and neutrons in an element. Whereas only the number of protons are represented in the Atomic Number.
What info could you use to determine the atomic number of an unknown element that has a mass number of 22?
In order to answer this, the number of neutrons must also be known. Subtract the number of neutrons from the mass number and the result is the atomic number. mass no. - no. of neutrons = atomic number (no. of protons)
Why would an elements atomic number change after transmutation?
Transmutation by definition means the conversion of one element into another, and so it follows that its atomic number must also change. Every element has a unique atomic number.
Is 11 the average atomic number for Sodium?
Yes: to be a sodium atom, an atom must have an atomic number of 11. Therefore, the average of all such numbers will also be 11.
In order to calculate the number of neutrons you must subtract the from the?
In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.
The target element of an x-ray machine must have a high enough atomic number so that?
The target element of an x-ray machine must have a high enough atomic number so that it has a high number of orbitalelectrons for the incident electrons to interact with. The higher the atomic number, the more orbital electrons that element will have. It must also have a high melting point and low rate of evaporation.
What is the number of neutrons protons and electrons in an atom of zirconium 90 that has no overall charge and an atomic number of forty?
Atomic number gives the number of protons: 40. If the atom is neutral, it must have an equal number of protons and electrons. Therefore, the number of electrons is also 40. The isotope number is the same thing as the atomic mass. Atomic mass is basically the sum of protons and neutrons. Therefore, subtracting the number of protons from the atomic mass yields the number of neutrons: (90 - 40 = 50). Thus, there are 50 neutrons.
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.

The number of neutrons in an atom is calculated by subtracting the atomic number from the atomic mass. In this case, for boron with an atomic mass of 11 and atomic number of 5, the number of neutrons would be 6.
What does the atomic number tell you about the parts of the element?
The atomic number of an element tells you the number of protons and neutrons that element has. Since an atom has a neutral charge, the number of electrons must equal the number of protons, so you can also tell the number of electrons that element has.
What must an atomic number with 8 have?
8 pariticals
