What is the element in period 4 with the smallest atomic radius?
The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.
What is the biggest element in the alkali family?
Francium has the biggest atomic weight and the biggest atomic radius between the alkali metals.
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.
Period 4 element with smallest atomic radius?
The period 4 element with the smallest atomic radius is chlorine, which has a greater number of protons in the nucleus pulling the electrons closer, making it smaller compared to other elements in the same period.
What element has the volume of 43 ml and the mass of 305.859?
There is no element with that atomic mass, the element that comes the closest is Ununbium with an atomic mass of 277.0.
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 atomic number of the most electronegative element?
the atomic number for flourine, the most electronegative element, is 9.
What is the relationship between atomic radius and the corresponding model radius?
Atomic radius refers to the size of an atom, while model radius is the size of the atom as represented in a molecular or atomic model. In most models, the model radius is larger than the atomic radius in order to make the structure more visible and distinguishable. The relationship between the two is that the model radius is typically proportional to the atomic radius but scaled up for clarity.
Which element would most likely have the Lewis dot symbol?
The element with the atomic number 17, which is chlorine, would most likely have the Lewis dot symbol because it typically gains one electron to achieve a stable electron configuration.
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.
