The electron configuration of polonium is [Xe]4f14.5d10.6s2.6p4.
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
Polnium is a posion
If you mean 1s22s22p3, you would refer to the periodic table. Using 2p3, you would look at the second period (row), look at the p block, and count 3 elements to the right to find nitrogen.
electron configuration with complete outer shells first three layers' limits are 2, 8, and 8
To determine the number of valence electrons in an atom using its electron configuration, look at the highest energy level (n) in the electron configuration. The number of electrons in this energy level is the number of valence electrons.
To determine the number of valence electrons from an electron configuration, look at the highest energy level (n value) of the electrons in the configuration. The number of electrons in this highest energy level is the number of valence electrons.
To determine the number of valence electrons in an electron configuration, look at the outermost energy level of the atom. The number of electrons in this level is the number of valence electrons.
Polonium has a metallic silvery appearance.

Sodium has 11 electrons, and one valence electron To achieve noble gas configurations, it would have to gain 7 electrons, for a total of 18 like Argon has. But this gain is impossible. So Sodium loses one electron to look like Neon which has 10.
Calcium. To get the answer easily, count up the electrons, then look for that atomic number on the periodic table
