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).

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 an atomic number of 19 and a mass number close to 39. To draw an atom of potassium, its important to know the following:Atomic number = number of protons = number of electronsMass number = number of protons + number of neutronsFrom this, we can work out the number of protons, neutrons and electrons in potassium:Protons in potassium = 19Electrons in potassium = 19Neutrons in potassium = 20Now, the protons and neutrons are located in the center of an atom called the nucleus so you would need to draw 19 protons and 20 neutrons at the center of the atom. Surrounding the nucleus are electrons that are located in sub-atomic shells. The electrons exist in an order that is called the electronic configuration. For the first 20 elements, the electronic configuration is 2, 8, 8, 2. You would therefore need to draw 4 "rings" around the nucleus. These rings will act as your sub-atomic shells. In the first ring, you would draw 2 electrons, followed by 8 electrons in the second and third ring, and finally 1 electron in the fourth ring.
Elements in the same group as potassium, such as lithium and sodium, also contain one unpaired electron. These elements are in group 1 of the periodic table and have similar electronic configurations.
what term describes elements that contain the same number of valence electrons

The potassium ion has 19 protons. In its neutral state, potassium has an atomic number of 19, which represents the number of protons in its nucleus. When it forms an ion by losing one electron to become positively charged, the number of protons remains the same.
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.

number of valence electrons (1). This gives them similar reactivity and allows them to form similar types of compounds.
A neutral potassium atom has 19 electrons.
