how many valence electrons are there in a neutral atom of potassium (k)?

Obviously, removing that electron gives us [Ar] (same configuration as K1+), which is a noble gas and has 8 electrons. Valence electrons are generally regarded as being 'the outermost electrons' for a given atom. Therefore, with neutral potassium, there is one valence electron.

Chloride ion, ie Cl- has total 18 electrons. Its configuration is 1s2 2s2 2p6 3s2 3p6. Thus it has 8 valence electrons.

That gives a total of 7 electrons, so neutral chlorine atoms have 7 valence electrons. The 10 remaining electrons, from the first and second shells, are core electrons.

Because the chlorate ion has a charge of -1, this ion contains one more electron than a neutral ClO3 molecule. Thus, the ClO3- ion has a total of 26 valence electrons.

As element 34, it has 34 electrons. 2+8+18 is 28. Therefore, six electrons are on its valence shell. It all depends on shells accepting an amount of electrons.

Potassium atom has just one valence electron and Chlorine has 7 electrons, Cl atom needs just one more electron to complete its octet, which it receives from K atom. So an ionic bond forms between potassium and chlorine and Potassium Chloride gets formed.

A neutral atom of calcium, atomic number 20, contains 20 protons and 20 electrons. It has zero net charge. We calculate the number of neutrons in an atom from its mass number and atomic number: Potassium has a mass number of 39 and an atomic number of 19.

This means that every atom of potassium has 19 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons. So the electron configuration of potassium will involve 19 electrons. The full electron configuration of potassium is 1s22s22p63s23p64s1 .

Best Answer: K is potassium. It has 1 valence electron Cl is chlorine, it has 7 valence electrons Since an atom needs 8 valence electrons to become stable.

How many total and valence electrons are in a neutral phosphorus atom? A neutral phosphorus atom has 15 total electrons. Two electrons can go into first shell, eight in the second shell, and it has five more in the third shell. The third shell is the outer valence shell, so it has 5 valence electrons.

A potassium atom, K is in its normal elemental state with 1 valence electron in it's most outer shell. It also has an equal amount of electrons and protons- 19 of each. However the potassium ion has lost it's valence electron and has therefore formed a positive action, K+ .
