How is the element with atomic number 82 in the periodic table different from the element in the atomic number 81?
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
How many elements have an atomic number greater than iodine?
i believe it is 57 do.If im wrong then im wrong im very sorry if i am.
What does elements with a higher atomic number than uranium have?
More electrons, protons, neutrons and a greater atomic weight.
What is the first transuranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
What is the atomic mass number of an isotope that has a atomic number of 6 but atomic mass of 5?
I think your understanding is confused. Atomic No. of '6' indicates the position in the periodic table, the number of protons, and the number of electrons. Atomic Mass is a number ( equal to or greater than atomic no.), which is the the total of protons and neutrons in the nucleus of an atom . So you atomic mass of '5' is incorrect as it is less than '6'. I think you mean 5 neutrons. If so the atomic mass is 6 + 5 = 11 This would be the isotopic element C-11 (Carbon eleven).
What is the mass number of Ca?
97% of the naturally occurring Calcium is isotope Ca-40, so massnumber 40. Other isotopes have massnumber 42 to 48
How atomic number is expressed?
The atomic number is equal to the number of protons of that particular element. Sometimes it is displayed as lower-left corner subscript, while the massnumber of an isotope of that element is displayed at the upper-left superscrip.Example: Uranium(235) is written as 92235Uor 23592U .
Can the atomic mass be greater than the atomic number?
Yes
How is the element with atomic number 82 in the periodic table different from the element in the atomic number 81?
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
What is bigger atomic mass or atomic number?
Atomic no.=no. of protons Atomic Mass=no. of protons+no. of neutrons Hence, atomic mass is greater
Why atomic mass is always greater than atomic number?
Atomic number indicates the number of protons in the nucleus of a given element, whereas atomic mass results from protons and neutrons.
Is hydrogens atomic number greater than heliums?
Hydrogen has atomic number 1 whereas helium's is 2.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
Why does the atomic radius decreases as the atomic number increases?
The atomic radius decreases as the atomic number increases due to the fact that there is now a greater quantity of protons in the nucleus emitting greater intramolecular force, pulling the electrons closer towards it. This, thus, decreases the radius.
What element has an atomic number that is six times greater than element beryllium?
The atomic number of beryllium is 4. The required element should have the atomic number 4x6=24. The corresponding element is Vanadium (V).Atomic number of Beryllium is 4. Six times of it is 24. Chromium has an atomic number of 24.
3 element with atomic number greater than 92?
#93 Neptunium See also the periodic table at the link below.
How are mass number and atomic number of an element related?
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
