What is the atomic number the atomic mass and the number of neutrons of the element hydrogen?
The 'standard' hydrogen atom has atomic number 1, Atomic Mass 1, no neutrons.
Although there are 2 other isotopes of hydrogen:
- (cant confirm name) which has atomic mass 2 and 1 neutron.
- (cant confirm name) has atomic mass of 3 and 1 neutron.
All isotopes have atomic number 1.
What else can I help you with?
What is the charge on an element with 0 neutrons and 1 proton and atomic number 1?
This is Hydrogen. Assuming it is not ionized it will have no charge.
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
What is the atomic mass number of hydrogen -3?
Hydrogen is a non meta element. Atomic mass of it is 2.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
What is the charge on an element with 0 neutrons and 1 proton and atomic number 1?
This is Hydrogen. Assuming it is not ionized it will have no charge.
Why is it impossible for the atomic number of element to be greater than its mass number?
The atomic number of an element is the number of protons in the nucleus of that element (and in any isotope of that element). The mass number of an element is the number of protons plus the number of neutrons in the nucleus of that element (and that number will differ for each isotope of that element). In any given element (save hydrogen) there are always one or more neutrons in the nucleus. As the atomic number is just the number of protons, it will always be less than the number of protons plus the number of neutrons. Always. The "outcast" is hydrogen. Most hydrogen has just a single proton in the nucleus. That means for those atoms of hydrogen, the atomic number (number of protons) and the mass number (number of protons plus the number of neutrons) will be one. (Recall that there are no neutrons in "regular" hydrogen.) Hydrogen does have two other isotopes. One has one neutron and the other has two neutrons. The atomic number for each of those two isotopes is still one, but their mass numbers will be two and three, respectively.
Does atomic weight is same with atomic number?
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
Which element's atomic number is the same as it's atomic weight?
Hydrogen, because it has one proton and no neutrons, thus has an atomic mass of 1, and is element 1.
What is the atomic number number of neutrons and the number of electrons of hydrogen?
Normal Hydrogen has an atomic number of 1, no neutrons and 1 electron.
How many neutrons are in the atom of Hydrogen?
The number of neutrons in a hydrogen atom will depend on which isotope of hydrogen we consider. Not all hydrogen atoms have the same number of neutrons. The vast majority of hydrogen atoms (over 99.98%) have no neutrons at all. Some have 1 (and this is called deuterium) and some have 2 (called tritium). These two isotopes occur naturally but are rare, as can be seen.To determine the number of neutrons in an atom, you must use the mass number, which is the sum of the number of protons and the number of neutrons. Since the atomic number of the element (for H, the atomic number is 1) tells you the number of protons, you can find the number neutrons by subtraction.See the Related Questions to the left for how to count the number of protons, neutrons and electrons in any atom of any element.
What element has 22 neutrons?
An element with 22 neutrons could be titanium. Titanium has an atomic number of 22, which means it has 22 protons in its nucleus. Since the number of neutrons is the difference between the atomic mass and the atomic number, an isotope of titanium with 22 neutrons would have a mass number of 44 (22 protons + 22 neutrons).
What is hydrogen's number of neutrons equals mass number - atomic number equals?
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).
Why can't the mass number be smaller than the atomic number?
The mass number has to be greater then the atomic number because the mass number is the protons plus the neutrons. If you were to take 10-12 you would get a negative number of 2 and there can't be a negative number of neutrons!
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
What is the atomic mass number of hydrogen -3?
Hydrogen is a non meta element. Atomic mass of it is 2.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
