# potassium valence electrons

you could also look up in the periodic table. In writing the electron configuration for Potassium the first two electrons will go in the 1s orbital. Again, the number of valence electrons increases from one to eight across the third period. Answer and Explanation: The atomic number of potassium is 19. Potassium has nineteen electrons, one more than the noble gas argon, so its configuration could be written as $$\left[ \ce{Ar} \right] 4s^1$$. Potassium (the neutral atom) has 19 electrons. For facts, physical properties, chemical properties, structure and atomic properties of the specific element, click on the element symbol in the below periodic table. Periodic Table of Elements with Valence Electrons Trends. We can determine the total number of electrons in the valence shell from the electronic configuration of the atom. The chemical symbol for Potassium is K. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Valence electrons are the electrons at the lastest shell. The electron valence is only one. It burns with a violet flame. The nucleus is composed of protons and neutrons. Potassium atoms have 19 electrons and 19 protons with one valence electron in the outer shell. Potassium consists of potassium atoms with their valence electrons delocalized throughout the metal, put those electrons still essentially "belong" to their atoms. Potassium is considered chemically similar to sodium, the alkali metal above it on the periodic table. It is so soft that it can be easily cut with a knife. For example in PO4 the valence number of oxygen (2) would be multiplied by 4 to give 8; the valency of phosphorus would simply be 5. The next six electrons will go in the 2p orbital. In the below periodic table you can see the trend of Valence Electrons. Potassium Chloride (KCl) Potassium Fluoride (PF) Potassium Iodide (KI) Interesting facts: It was the first metal to be isolated using electrolysis. It is found in all living plant and animal cells. Potassium is in the 1st group,so it has one valence electron. Potassium is a chemical element with atomic number 19 which means there are 19 protons and 19 electrons in the atomic structure. Since 1s can only hold two electrons the next 2 electrons for Potassium go in the 2s orbital. The fourth and subsequent periods follow the same pattern except for using a different noble gas. Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements.. So it should be one in this case. Characteristics and Properties Under standard conditions potassium is a soft silvery-white metal. The Ionic bond formed between Potassium and Bromine is created through the transfer of electrons from Potassium (metal) to Bromine (nonmetal). The p orbital can hold up to six electrons. Potassium is located in group 1 which means that potassium has one valence electron; Bromine is located in group 17 which means that it has seven valence electrons. It catches fire when exposed to water. The number of valence electrons in an atom governs its bonding behavior. Across the third period outer shell and Explanation: the atomic number valence...
