What is the atomic number and atomic mass number for aluminum?
The numbers of protons and electrons in any neutral atom are the same as the atomic number, 13 for aluminum. The number of neutrons varies by isotope and can be found by subtracting the atomic number from the atomic mass number. One isotope is Al-27, in which there are 14 neutrons.
What is the atomic number of neon 22?
The atomic number of any isotope of neon is 10.
Which number in the element key is the atomic number?
The "Atomic Number" is the number of protons in the nucleus of any atom.
How are the atomic number and mass number of a nuclide affected by the emisson of gramma radiation?
Any change of the atomic number.
Oxygen has eight protons eight neutrons and eight electrons what is the atomic mass?
For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.
Why is hydrogen given the number one?
Hydrogen is given atomic number 1 because it has the lowest atomic mass of any element.
Which metal has the lowest number of proton in its atom?
Lithium has the lowest number of protons of any metal: 3. Hydrogen an helium have fewer protons bu they are not metals.

What is the atomic number of a dime?
Any atomic number for a dime.
What is the atomic number of S-2?
The atomic number of sulfur is 16 The number of protons is the same as the atomic number. The S-2 gains 2 electrons so it changes from 16 to 18. The atomic mass is 32. The atomic mass number minus the number of protons will give you 16 which is the number of neutrons. :)
What is the number of protons for platinum?
Platinum is a metal element. Atomic mass of it is 195.08.
What is the difference between silver and tin?
Silver and tin are two different elements. Silver has an atomic symbol of Ag and an atomic number (proton number) of 47. It is a lustrous white metal and has the highest thermal conductivity of any metal and electrical conductivity of any element. It is also very ductile and malleable. Tin has an atomic symbol of Sn and an atomic number of 50. It is also ductile and malleable, but oxidizes very easily. As such, it is usually coated over other metals to prevent corrosion.
What are the lowest multiples of three?
The lowest multiple of any number is the number itself.
What are the lowest multiples of 18?
The lowest multiple of any number is the number itself.
What is the atomic number of neon 22?
The atomic number of any isotope of neon is 10.
Which number in the element key is the atomic number?
The "Atomic Number" is the number of protons in the nucleus of any atom.
What element has the lower atomic number of any group?
Trick question? Lowest group is 1? There is no zero. If it's not a trick question then it's Hydrogen.
