Potassium (K) has an atomic number of 19, which means it has 19 electrons. The arrangement of these electrons in the K, L, and M shells is as follows: the K shell (first shell) holds 2 electrons, the L shell (second shell) holds 8 electrons, and the M shell (third shell) holds the remaining 9 electrons. Therefore, the electron configuration can be summarized as 2 electrons in K, 8 in L, and 9 in M.

When k plus and l- combine - bond results?
When a K⁺ ion (potassium) combines with an L⁻ ion (which could represent a generic anion, like chloride, Cl⁻), an ionic bond results. This occurs due to the transfer of an electron from potassium, which has a low ionization energy, to the anion, which has a high electron affinity. The electrostatic attraction between the positively charged K⁺ and negatively charged L⁻ creates a strong ionic bond, resulting in the formation of an ionic compound. This process exemplifies how metals and nonmetals interact to achieve stable electron configurations.
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 ofthe K+ion: 18 in total, (K,L,M,N orbits) => 2, 8, 8, 0 resp. in each orbit.
What is the correct set of four quantum numbers for the valence electron of potassium Z?
The atomic number of potassium (K) is 19, and its electron configuration is [Ar] 4s¹. The valence electron of potassium is in the 4s orbital. Therefore, the correct set of four quantum numbers for this valence electron is: n = 4 (principal quantum number), l = 0 (angular momentum quantum number for s), m_l = 0 (magnetic quantum number), and m_s = +1/2 or -1/2 (spin quantum number, typically +1/2 for the single valence electron).
What s the electron configuration of potassium?
First, you have to look at the noble gas on the row above potassium, [Ar] then you have to write the shorthand electron configuration which would be simply 1s1. Your final answer would be [Ar]1s1
When are klmn orbitals used for electron configuration?
K, L, M, and N orbitals refer to different energy levels and sublevels in an atom where electrons are found. Specifically, the K shell corresponds to the first energy level (n=1), L to the second (n=2), M to the third (n=3), and N to the fourth (n=4). These orbitals are used in electron configurations to describe the arrangement of electrons in an atom, following the Aufbau principle, Pauli exclusion principle, and Hund's rule. They help to determine the chemical properties and reactivity of elements based on their electron distribution.

Electron arrangement for sodium?
The electron arrangement for sodium is 2-8-1. This means that sodium has 2 electrons in the first energy level, 8 electrons in the second energy level, and 1 electron in the third energy level. Sodium has 11 electrons in total.

Is the first electron shell called the L shell?
No, its called the K, then the L is after it and then the M and so on. On the periodic table, the period an element is in is how many electron shells it has.
What kind of bond will KCI form?
Potassium chloride (KCl) will form an ionic bond. This is because potassium has a tendency to lose an electron to achieve a stable electron configuration, while chlorine has a tendency to gain an electron. As a result, potassium becomes a positively charged ion (K+) and chlorine becomes a negatively charged ion (Cl-), leading to the formation of an ionic bond between them.

Does oxygen or sulfur have more electron shells?
Oxygen is on period 2 whereas sulfur is on period 3. Therefore, sulfur has more electron shells than oxygen.

ANSWERED How many g of potassium must react with H20 to produce 1.60 L of H2 at STP according to the following equation?
Given the reaction 2K + 2H2O -> 2KOH + H2, we can see that 2 moles of potassium react to produce 1 mole of hydrogen gas. At STP, 1 mole of any gas occupies 22.4 L. Therefore, for 1.6 L of hydrogen gas, 2 moles of potassium are needed, which is approximately 155 g of potassium.
