What is electronic configuration of potassium having atomic number 19 is?
Potassium with atomic number as 19 have its electronic configuration as 2,8,8,1 not as 2,8,9 because the energy of 4s orbital is less than 3d orbital,so 4s orbital is filled first.
What element has A atomic number 19?
Potassium
Potassium – Element information, properties and uses | Periodic Table.
What is the electron configuration for potassium atomic number 19 quizlet?
The electronic configuration of potassium is [Ar]4s1.
What is the group of element 19?
19 is in group 1st and period 4th. Note: Valence electrons are the electrons present in the highest energy level, here the highest energy level is 4s, and hence only one electron is present there. The element with 19 atomic no. is Potassium.
What isotope has an atomic number of 19?
You now know that the most abundant isotope of potassium contains 20 neutrons. All isotopes of potassium will have the same number of protons inside their nucleus, i.e. 19 protons.
What is the element with the electron configuration 1s22s22p63s23p5?
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
What is the symbol for the ion with 19 protons and 18 electrons?
Answer and Explanation: The symbol for the ion with 19 protons and 18 electrons is K+.
Which statement is correct for the element of proton number 19?
The element with atomic number 19 is K, and is thus present in group 1A.
Is atomic number 19 a metal or nonmetal by?
The element having atomic number 19 is potassium. The chemical symbol for potassium is K. Potassium is an alkali metal and it belongs to group 1 of periodic table.
What is the atomic mass number of an element that has 19 protons 19 electrons and 20 neutrons?
Hence, number of neutrons is 39 – 19 which is 20. Potassium-40 – It has 19 protons and atomic mass is 40.

What is the valency of potassium atomic number 19 )? Explain how we determine its valency from its atomic number?
The electronic configuration of potassium is 2,8,8,1. The valence shell contains 1 electron therefore the valency of potassium is 1.
What is the mass number of an atom that contains 19 protons 19 electrons and 20 neutrons?
In which group and period does the atomic number 19 belong?
So the element with atomic no. 19 is in group 1st and period 4th. Note: Valence electrons are the electrons present in the highest energy level, here the highest energy level is 4s, and hence only one electron is present there.
What is the atomic number of an atom with 19 protons 19 electrons and 21 neutrons?
Potassium-40 – It has 19 protons and atomic mass is 40. Hence, number of neutrons is 40 – 19 which is 21.

How do you find the actual configuration of an atom?
Actual configurations have not been verified. The electron configuration states where electrons are likely to be in an atom. If you don’t have a chart, you can still find the electron configuration. Use the element blocks of the periodic table to find the highest electron orbital.
