Period 4 element with smallest atomic radius?
It is krypton as it the far most right on the periodic table, having the smallest radius
What is the larger element in the alkali metal family?
Francium has the most larger atomic weight and also the largest atomic radius between the alkali metals.
What is the heaviest lanthanide?
The smallest atomic number and atomic weight for a lanthanide is lanthanum itself, element 57. The smallest atomic size is lutecium element 71; the lanthanides steadily decrease in atomic radius through the series, and the smallest is the last of them.
What is the nineteenth element in the periodic table of elements?
Most likely, this is Potassium's (K) atomic number.
What is the element in period 4 with the smallest atomic radius?
Potassium is the period four element with the lowest mass; its average mass is 39.0983amu.
What is the atomic number of the most electronegative element?
the atomic number for flourine, the most electronegative element, is 9.
What is the atomic radius?
The atomic radii is an estimation of the radius of an atom. The value of the atomic radii is based off an approximation of the distance from the atom's nucleus to the edge of the atom's electron cloud.
What element in row 6 of the periodic table has the largest atomic radius?
Cesium (Cs), atomic number 55, has the largest atomic radius in period 6.Only francium (row 7) may be larger, but testing is difficult because francium does not exist in any meaningful amounts (maybe 30 g on the entire Earth).
What is the factor that affects the atomic number in an element?
More shielding of the outer electrons by the inner electrons is the most important factor that affects the atomic number in an element. A valence electron in an atom is attracted to the nucleus of an atom and is repelled by the other electrons in the atom. The inner electrons shield the outer electrons from the attraction of the nucleus and cause the atomic radius to be larger.
What element is most likely to be produced as a result of a fission reaction using uranium-235 as a fuel?
There are about 50 that form, the 2 groups most likely are ones with Atomic Mass numbers near 95 and 140.
Why does indium have the largest atomic radius?
It doesn't. Francium has the largest atomic radius because it has the most energy levels in period seven of the periodic table, and the least number of protons.
Why is a new element most likely metal?
A new element is most likely metal because it gives people the most boners
