The nucleus is an electron, but in the outermost shell (= valence electron).
The atomic number (Z) of potassium is 19.
Therefore its electron distribution is 1s2 2s2 2p6 3s2 3p6 4s
The valence electron is 4s, so the nucleus is 1s2 2s2 2p6 3s2 3p6.
The potassium ion, K+, has lost one of its outermost electrons, so it has the same electrons as the nucleus of K.
The atomic core of potassium ions is frozen permafrost in the Earth's mantle to inner core.

The symbol for a potassium ion is K+ The charge is +1 because potassium is in the first group on the periodic table.

Potassium, or K, has an atomic number of 19. Therefore, its electrically neutral form would have 19 protons and 19 electrons. An ion of potassium, labeled K+, has had one of its electrons removed; therefore it only has 18 electrons.

you should just turn go look it up in a book or something! Really its not that hard!

A superscript before the K (which is potassium) represents the atomic mass; a subscript before the K represents the atomic number. Therefore, 3919K represents "potassium-39", which is potassium's most abundant isotope. 4019K would represent "potassium-40", which is another, less abundant isotope of potassium.
The potassium ion is K+ and the sulfate ion is SO42-
The Chemical Formula for Potassium Ion is K+.
