Beryllium or Be is the smallest of group two. you can find atomic radius by: the farther down you go the higher it is lowest is at top and then goes to the right. so the top five lowest atomic radius are in order; He, Ne, F, O, N.
The atomic number of the Periodic Table element Period is 92.
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.
The atomic number of the element with the symbol Li, located in period 3 on the periodic table, is 3.
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.
The element's location on the periodic table indicates its period, which corresponds to the number of electron shells in its atomic structure.
The atomic number of the Periodic Table element Period is 92.
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.
The atomic number of the element with the symbol Li, located in period 3 on the periodic table, is 3.
Fluorine
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.
The element's location on the periodic table indicates its period, which corresponds to the number of electron shells in its atomic structure.
In a given period, the element with lowest atomic mass will belong to group 1. It should also be noted that lithium is the metal with the smallest atomic mass.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
Presumably because atomic number is the fundamental characteristic for organizing the periodic table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.
Neon element in the periodic table period 2 has most mass.It has atomic mass of 20.17.It is colorless and odorless.
Lithium(520)
The element with the smallest atomic size is Argon (Ar) as it has the highest atomic number among the options given. Atomic size generally decreases from left to right across a period in the periodic table.
