How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
What element has an atomic mass of 4.0?
The element with an atomic mass of 4.0 is helium. Helium has an atomic number of 2, which means it has two protons in its nucleus. It also has two neutrons, giving it an atomic mass of 4.0.
What is lithium atomic mass?
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.
What would you expect the atomic mass of a helium atom to be Explain your answer?
The atomic mass of a helium atom is approximately 4 atomic mass units (amu). This value reflects the combined mass of its two protons and two neutrons, as helium has two protons in its nucleus and typically two neutrons. The mass of electrons is negligible compared to that of protons and neutrons, so it does not significantly affect the atomic mass. Thus, the expected atomic mass aligns closely with the sum of the nucleons in the helium nucleus.
What two elements have an atomic mass of 1?
only one element (hydrogen) has the atomic mass of 1.
What two pieces of information can be determined from the atomic mass?
The number of protons and neutrons in the atom can be determined from the atomic mass. The atomic mass represents the average mass of the isotopes of that element in atomic mass units.
What are two use of nonmetallic mineral?
what are two uses of nonmetallic mineral resources
What is the atomic mass on the periodic table?
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
Can the atomic number be multiplied by two then equal the atomic mass?
Not generally. For light elements this relation is often approximately true, but for heavier elements, the gram atomic mass is more than two times the atomic number, as the ratio of neutrons to protons increases with increasing atomic mass.
What is the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
What is the atomic mass for alpha radiation?
The same as for a helium nucleus: 4. Two protons and two neutrons.
What two elements whose atomic mass order does not match their atomic number order?
The two elements that exhibit a discrepancy between atomic mass order and atomic number order are potassium (K) and argon (Ar). Potassium has an atomic number of 19 and an atomic mass of about 39.1, while argon has an atomic number of 18 and an atomic mass of approximately 39.9. This means that argon, which is lighter in terms of atomic mass, appears after potassium in the periodic table based on atomic number.
