Electron dot diagrams show the number of valence electrons and whether they are paired or unpaired. One of the trends of the Periodic Table is that elements within the same group have the same number of valence electrons. Sodium and potassium are in the same group.
It's because potassium and sodium [salt] are in the same group on the periodic table. A group is all the list of elements going vertical in that section. A period is all the elements going horizontal. Hope I helped:]
Potassium's 1 valence electron is farther away from its nucleus than sodium's 1 valence electron is from its nucleus. Potassium is one period up from sodium (well, down on the p.t.e., but up in number of energy levels), so the attraction between potassium's nucleus and outermost electron is a little less than in sodium, so that electron is more likely to go flying, which makes potassium more reactive.

All have the same number of valence electron (i.e., one).
When number of sodium-potassium pump decreased, transport of Na takes little more time. Less number of sodium-potassium more time for transport

No. They both are looking to lose an electron. One will bond with an element that will take that electron. Potassium and iodine will form ionic bonds.
They have one valence electron.
Because they have similar electron configurations.
When number of sodium-potassium pump decreased, transport of Na takes little more time. Less number of sodium-potassium more time for transport
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.

Sodium and potassium are both highly reactive because they have only one outer shell electron which they lose very easily to form Na+ and K+ ions respectively. The sodium and potassium in the body are already in the form of these ions.
The charge of an atom depends on the number of protons and the number of electrons. If the number of protons and electrons is the same, which is generally regarded as the normal state, then the atom will be neutral with no charge. If there is a difference in the number, then the charge will be equal to the number of protons minus the number of electrons. As an example, both sodium and potassium will commonly lose one electron to form an ion with a +1 charge. A neutral sodium atom has 11 protons and 11 electrons while potassium will have 19 of the same. Sodium loses an electron leaving it with 10 electrons. 11-10=1. Potassium loses an electron, leaving it with 18 electrons. 19-18=1.
No,sodium has an atomic number of 11 therefore it has 11 electrons with the electronic configuration 2,8,1whereas potassium has 19 electrons with an electronic configuration of 2,8,8,1They both have different numbers of electrons but have the same number of electrons in their 'valence' shell ( outer most shell) as they are both in Group 1
