The element Potassium has an atomic number of 19 and an atomic mass of 39 Draw the ion that forms when it gains or loses an electron or electrons?
All metals only can loose some electrons, which is only ONE in the case of potassium.
Electron configuration of K: 19 in total, (K,L,M,N orbits) => 2, 8, 8, 1 resp. in each orbit.
- K ==> K+ + e-
This is the preferred (thus more stable) electron configuration of
the K+ion: 18 in total, (K,L,M,N orbits) => 2, 8, 8, 0 resp. in each orbit.

How many 3d electrons are in the atom K element?
The element potassium (K) has an atomic number of 19, which means it has 19 electrons. In its electron configuration, potassium is represented as (1s^2 2s^2 2p^6 3s^1). Since potassium has no electrons in the 3d subshell, it has 0 3d electrons.
How many electrons does an atom potassium havew?
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.
How many 3d electron are in potassium?
Potassium (K) has an atomic number of 19, meaning it has 19 electrons. The electron configuration for potassium is 1s² 2s² 2p⁶ 3s¹. In this configuration, there are no electrons in the 3d subshell; therefore, potassium has 0 electrons in the 3d orbital.
The element potassium has an atomic number of 19 this means that potassium?
The atomic number indicates the number of protons (19) and electrons (19).
How do you find the number of electrons in element?
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
Electrons of the 19th element?
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
How many 3d electrons are in the atom K element?
The element potassium (K) has an atomic number of 19, which means it has 19 electrons. In its electron configuration, potassium is represented as (1s^2 2s^2 2p^6 3s^1). Since potassium has no electrons in the 3d subshell, it has 0 3d electrons.
How many number of electron does potassium have?
Potassium, a chemical element with the symbol K and atomic number 19, has 19 electrons. In a neutral potassium atom, the number of electrons is equal to the number of protons in the nucleus, which is 19. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom in specific energy levels or shells.
How many electrons potassium ion?
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.
How many electrons does an atom potassium havew?
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.
Potassium (K) has an atomic number of 19. It often forms an ion by losing 1 electron. How many electrons would the ion have?
The ion of potassium (K) would have 18 electrons after losing 1 electron. This is because the element loses 1 electron to achieve a stable electron configuration, similar to the nearest noble gas (argon) with 18 electrons.
What is the element with a valence electron configuration of 2s2 2p4?
Bromine has 7 electrons in its fourth energy level.
What element has the ground-state electron configuration of Ar4s23d6?
The element with that electron configuration is Iron.
How many 3d electron are in potassium?
Potassium (K) has an atomic number of 19, meaning it has 19 electrons. The electron configuration for potassium is 1s² 2s² 2p⁶ 3s¹. In this configuration, there are no electrons in the 3d subshell; therefore, potassium has 0 electrons in the 3d orbital.
Does potassium have more electrons than uranium?
No, potassium does not have more electrons than uranium. Potassium has 19 electrons, while uranium has 92 electrons. This is because the atomic number of an element determines the number of protons and electrons it has, and uranium has a higher atomic number than potassium.
The element potassium has an atomic number of 19 this means that potassium?
The atomic number indicates the number of protons (19) and electrons (19).
What element has the electron configuration 1s22s22p23s23p2?
The element with this electron configuration is carbon (C). This electron configuration corresponds to 6 electrons, which is the atomic number of carbon.
