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 number and mass number of deuterium 2H?
As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
What properties did mendeleev use to arange the the periodic table?
He used mass,what they react to and there proertys
What are the atomic mass of elements rarely whole numbers?
1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers.2. Second cause: also occurs the so-called mass defect.Not atomic mass for elements; atomic weight is correct.
What is the atomic mass in Hindi?
The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units.[1] The atomic mass is the total mass of protons, neutrons and electrons in a single atom.[2]The atomic mass is sometimes incorrectly used as a synonym of relative atomic mass, average atomic mass and atomic weight; these differ subtly from the atomic mass. The atomic mass is defined as the mass of an atom, which can only be one isotope at a time and is not an abundance-weighted average as in the case of atomic weight. In the case of many elements that have one dominant isotope the actual numerical similarity/difference between the atomic mass of the most common isotope and the relative atomic mass or standard atomic weights can be very small such that it does not affect most bulk calculations-but such an error can be critical when considering individual atoms. For elements with more than one common isotope the difference even to the most common atomic mass can be half a mass unit or more (e.g. chlorine). The atomic mass of an uncommon isotope can differ from the relative atomic mass or standard atomic weight by several mass units.
What periodic element has a mass of 50.9?
Three elements (isotopes) are known to have an atomic mass of 39.96:Ar-40 (99.6%), K-40 (0.01%) and Ca-40 (96.9%).(Percentage value of naturally occurring in elements.)
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.
In modern periodic table the elements are designed on ascending seris of 1. atomic mass 2. mass number 3. atomic number 4. electromic configuration?
Atomic number = number of protons.
What is the atomic number and mass number of deuterium 2H?
As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
What is the mass of one mole of Al2O3 if aluminum has an atomic number of 13 and an atomic mass of 26.98 and oxygen has an atomic number of 8 and an atomic mass of 16.00?
The mass of one mile of a compound is found by adding up the atomic masses of each of the component elements. A mole of Al2O3 has mass of 2 × 26.98 + 3 × 16.00 = 101.96g

Is the atomic mass equal to the molar mass?
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.

What is equal to the mass of the atom?
the atoms of different elements weigh different.it depends as to which element you are referring to.for example an element with the atomic mass 4 can be matched by 2 atoms of a lighter element with the atomic mass 2
What is the symobel and atomic number and atomic mass for helium?
Symbol: He atomic #: 2 atomic mass: 4.002602
How do you find molar mass?
you need to find the relative atomic mass. without that, you can't find that information unless given to you. basically, molar mass is a mole. a huge unit, but if you have that one "mole" of hydrogen atoms, you will have a equivalent of 1 gram The molar mass is the sum of the atomic weights of elements contained in the molecule, expressed in g/mole.
