What is the atomic number and atomic mass number of chlorine?
The atomic number of chlorine is 17, which indicates the number of protons in its nucleus. The atomic mass number of chlorine is about 35.5, which represents the average mass of its isotopes considering their relative abundances.
What is the name of the element with an atomic mass of 197?
The element with an atomic mass of 197 is Gold.
Do you need atomic number to find atomic mass?
No, you do not need the atomic number to find the atomic mass of an element. The atomic mass is the weighted average of the masses of the isotopes of an element, whereas the atomic number is the number of protons in the nucleus.
What element has a 27 atomic mass?
The element with an atomic mass of 27 is cobalt (Co). Cobalt is a transition metal found in the periodic table with atomic number 27.
Is the atomic weight of chlorine 35.5 because of electrons?
No, the atomic weight of chlorine (35.5) is determined by the combined average weight of its protons, neutrons, and electrons. The fractional atomic weight is due to the existence of isotopes of chlorine, with chlorine-35 being more abundant than chlorine-37.
What is the atomic number and atomic mass number of chlorine?
The atomic number of chlorine is 17, which indicates the number of protons in its nucleus. The atomic mass number of chlorine is about 35.5, which represents the average mass of its isotopes considering their relative abundances.
Which element have the atomic mass of 1?
The only such element is hydrogen.
What is the name of the element with an atomic mass of 197?
The element with an atomic mass of 197 is Gold.
What two elements have an atomic mass of 1?
only one element (hydrogen) has the atomic mass of 1.
What is the atomic mass for oxide?
It doesn't have an Atomic Mass, it is not an element (pure substance) it is a compound and therefore only has a molar mass.
Do you need atomic number to find atomic mass?
No, you do not need the atomic number to find the atomic mass of an element. The atomic mass is the weighted average of the masses of the isotopes of an element, whereas the atomic number is the number of protons in the nucleus.
What element has a 27 atomic mass?
The element with an atomic mass of 27 is cobalt (Co). Cobalt is a transition metal found in the periodic table with atomic number 27.
Is the atomic weight of chlorine 35.5 because of electrons?
No, the atomic weight of chlorine (35.5) is determined by the combined average weight of its protons, neutrons, and electrons. The fractional atomic weight is due to the existence of isotopes of chlorine, with chlorine-35 being more abundant than chlorine-37.
How do you calculate average atomic masses of elements?
To calculate the average atomic mass of an element, multiply the atomic mass of each isotope by its abundance (as a decimal) and then sum these values for all isotopes of that element. This will give you the weighted average of atomic masses for that element.
What is the atomic mass for the element carbon is 12.011?
the atomic mass of just pure carbon would be twelve. the atomic mass is only effected by the number of protons and numbers of nuetrons
Which element has an atomic mass of11?
Atomic mass numbers are not properties of elements overall, but only of particular isotopes of elements. The only stable element with an isotope with mass number 11 is boron. Beryllium and carbon also have isotopes with mass number 11, but these are radioactive.
How do you find the number of neutrons in a element using only mass and the element name?
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
