18
(Atomic Number:19 minus the group number:1)
19-1=18 core electrons
A potassium ion (K+) has 18 electrons. Potassium has 19 electrons in its neutral state, but when it loses one electron to become an ion, it has 18 electrons.
Potassium is a non metal element. There are 19 electrons in a single atom.
Oxygen has 6 core electrons.
Potassium has 19 protons, 19 electrons and 20 neutrons.
Finding the number of electrons in an atom is easy. You just have to know the atomic number of the element. The atomic number for Potassium is 19. That means Potassium has 19 electrons.
The neutral atom of potassium has 19 electrons.
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
the valency of potassium is 1
Oxygen has 6 core electrons.
Tin has 46 core electrons.
A potassium ion (K+) has 18 electrons. Potassium has 19 electrons in its neutral state, but when it loses one electron to become an ion, it has 18 electrons.
Germanium has 18 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Potassium is a non metal element. There are 19 electrons in a single atom.
Oxygen as 2 core electrons and 6 valence electrons.
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Oxygen has 6 core electrons.
Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.
