What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
How can you get the mass number and atomic number of element?
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
What is the atomic mass of an element equal to atomic number or number of protons?
Answer:The atomic mass is NOT equal to both 'atomic number' and 'number of protons .The atomic mass of an element is by approximation equalto, but not exactly, the sum of protons and neutrons in the nucleus of the atom.The number of protons is given by the atomic number, not atomic mass.So, only the atomic number of an element AND the number of protons are equal. The atomic mass is also depending on the number of neutrons.More explicative:The atomic mass of an element refers to a particular isotope of that element, and is equal to the sum of the protons and neutrons in the nucleus of atoms of that isotope.For example, carbon-12 atoms have 6 protons and 6 neutrons, while carbon-14 atoms have 6 protons and 8 neutrons.Atomic weight, which is shown on the Periodic Table is a weighted average of the atomic masses of all the different isotopes of each element.For example, the atomic mass of C-12 is 12.0000 a.m.u. and the atomic mass of Carbon is 12.0107(8) g/molFrom the Periodic Table you can only tell the number of protons in the atoms of all of the isotopes of a given element, because the number of protons defines the element, and is the element's atomic number. However, you cannot tell the number of neutrons from the Periodic Table. You would have to look up the atomic masses of all the isotopes of each element in some sort of reference. The atomic number of an element is equal to the number of protons in the nucleus of an atom.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
The number of protons in an atom is called the atomic mass of the element?
The mass number is the sum of protons and neutrons in the atomic nucleus. The number of protons is equal to the atomic number.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
Which is always equal to the molar mass of any element?
The atomic mass of an element is equal to its molar mass in grams/mol.
What element is equal to the atomic mass?
Hydrogen
The molar mass of an element is equal to?
The element's average atomic mass.
Which of these is always equal to the molar mass of any element?
This is sum of the atomic weights of elements contained in the formula.
What does the atomic mass of an element equal to?
no. of protons in its neucleus
How many atoms are in an element whose mass is equal to the atomic mass?
1
Is the atomic mass equal to the number of atoms in the elements?
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
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.
Does the number of protons in an atom of an element always equal its atomic weight?
atomic weight = mass of protons + mass of neutrons
What is the relationship between the atomic mass of an element and a mole of that elements atoms?
The mole is the atomic weight expressed in grams.
