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?
When Potassium (K) gains one electron, it forms a positive ion with a charge of +1, written as K+. The electron configuration becomes 1s^2 2s^2 2p^6 3s^2 3p^6. When Potassium loses one electron, it forms a negative ion with a charge of -1, written as K-. The electron configuration becomes 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1.
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
What is the chemical name for KCIO4?
There is no such thing as KCIO3. That should be a lowercase L, not an I. (all two-letter element symbols use a lowercase for the second letter) That being said, KClO3 is Potassium Chlorate. K = Potassium Cl = Chlorine O = Oxygen 3 = number of Oxygen atoms in the molecule
What letter represents an electron?
There are 7 different letters, each to represent each shell. They are: 1. K 2. L 3. M 4. N 5. O 6. P 7. Q
What is the electron configuration of a neutral atom of oxygen?
Orbital 'fill up' of Oxygen (atom number 8) (K) = 2 electrons (L) = 6 electrons
Electron arrangement for sodium?
The normal electron arrangement of sodium(Na) in K, L and M shells is 2, 8, 1 and the electronic configuration of the metal in its sub-shells is 1s2 2s2 2p6 3s1.

What characteristic electron configuration are shared by Lithum sodium Potassium and Rb?
suborbital (l)

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.
How many shells in lithium?
The number of electron shells in a normal Lithium atom is 2. It has an electron configuration of 1s22s1
How many electron shells do the atoms of elements in the second period have?
two K and L
What are the ions of kci?
kci does not exist in chemistry. but KCl (with a lowercase L) is potassium chloride It contains potassium ions (K+) and chloride ions (Cl-)
ANSWERED How many g of potassium must react with H20 to produce 1.60 L of H2 at STP according to the following equation?
You need the balanced chemical reaction equation :------------------------------------------------------------------------2 K + 2 H2O ----. 2 KOH + H2moles H2 = n H2 = ( 1.60 L ) ( 1 mol H2 / 22.4 L H2 ) = 0.07143 moles H2moles K = n K = ( 0.07143 mol H2 ) ( 2 mol K / 1 mol H2 ) = 0.14286 moles Kmass K = m K = ( 0.14286 mol K ) ( 39.10 g K / mol K )mass K = m K = 5.56 g of potassium
Is CH3CN a ionic bond?
KCI is not a real compound. Potassium, carbon, and chlorine will not bond together. However, if that I were an L, the compound would be KCl (potassium chloride). KCl is a real compound, and it is ionically bonded.
What is the electron arrangement for a lithium atom?
It starts with the following: K shell - 2 electrons L shell - 8 electrons M shell - 18 electrons N shell - 32 electrons it works out from there K being the first etc.

There is no such thing as KCIO3. That should be a lowercase L, not an I. (all two-letter element symbols use a lowercase for the second letter) That being said, KClO3 is Potassium Chlorate. K = Potassium Cl = Chlorine O = Oxygen 3 = number of Oxygen atoms in the molecule
