All the elements in the first column of the Periodic Table have 1 valence electron.
They include: lithium (Li), sodium (Na), postassium (K), rubidium (Rb),cesium (Cs), and Francium (Fr).
See the Related Questions for more information.
All elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
The alkali metals or group 1 elements (lithium, sodium, potassium, rubidium, cesium, francium) will have one valence electrons, so they all will have similar properties.
All of the others in column 1 of a wide form periodic table: lithium, sodium, rubidium, cesium, and francium.
Sodium and other alkali metals as: lithium, rubidium, caesium.
Only potassium has the same electron configuration as potassium.
The number of elements that contain the same type of outer electrons as sodium is 11.
Lithium, Rubidium, Cesium, Francium.
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.
The atomic nucleus of potassium has 19 protons and a number of neutrons specific for each isotope (from 13 n to 36 n).
Potassium has 4 orbitals. The atomic number of potassium is 19, therefore, potassium has 19 electrons. Orbital 1 holds 2 electrons, Orbital 2 holds 8 electrons, Orbital 3 holds 8 electrons, and Orbital 4 holds 1 electron. *Note: Potassium has 1 valence electron.

what term describes elements that contain the same number of valence electrons
The number of elements that contain the same type of outer electrons as sodium is 11.
All of the elements in group 1 on the periodic table contain the same number of outer electrons as sodium, which is 1.

There are 19 protons in a potassium atom, ion, and isotope. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons.
Finding the number of electrons in an atom is easy. You just have to know the atomic number of the element. The atomic number for Potassium is 19. That means Potassium has 19 electrons.
An example is silicon.
