Argon has a lower atomic number than potassium because it has fewer protons in its nucleus. However, argon has a greater mass number than potassium because it has more neutrons in its nucleus. The mass number of an atom is determined by the sum of protons and neutrons in its nucleus.
i believe it is 57 do.If im wrong then im wrong im very sorry if i am.
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.
An element that is 3 times greater than oxygen is sodium (Na) with an atomic number of 11 and an atomic mass of approximately 23. It is located in the third period and the third group of the periodic table, making it 3 times heavier than oxygen (O) with an atomic number of 8 and an atomic mass of around 16.
Elements with a higher atomic number than uranium belong to the transuranium elements, which are all man-made and generally unstable due to their high atomic numbers. These elements typically undergo radioactive decay, leading to the formation of lighter elements.
The atomic radius decreases from left to right and increases from top to bottom
97% of the naturally occurring Calcium is isotope Ca-40, so massnumber 40. Other isotopes have massnumber 42 to 48
Yes
The element with the greater atomic number will have a greater atomic mass. Atomic mass is the sum of the protons and neutrons in an atom's nucleus, and since the number of protons increases with atomic number, so does the atomic mass.
#93 Neptunium See also the periodic table at the link below.
Chromium (Cr), which has an atmoic number of 24. Beryllium has an atomic number of 4, so 4*6=24, which is Chromium.
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 .
Atomic no.=no. of protons Atomic Mass=no. of protons+no. of neutrons Hence, atomic mass is greater
Hydrogen has atomic number 1 whereas helium's is 2.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
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.
Platinum has an atomic number of 78. If you increase the atomic number by one, you find Gold, with an atomic number of 79.
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.
