The elements potassium (K), rubidium (Rb), and cesium (Cs) each contain the same number of atomic shells as sodium.
Elements in the same group as sodium on the periodic table, such as lithium and potassium, also contain the same number of outer electrons (1) as sodium. These elements belong to Group 1 or the alkali metals group, and they share similar chemical properties due to their outer electron configuration.
The molar masses of any two elements contain the same number of moles.
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
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
Elements in the same group as sodium (Group 1) all contain the same number of outer electrons, which is one. Therefore, there are six elements in the same group as sodium: lithium, potassium, rubidium, cesium, francium, and hydrogen.
group
The elements potassium (K), rubidium (Rb), and cesium (Cs) each contain the same number of atomic shells as sodium.
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.
An example is silicon.
Elements in the same family, or group will contain the same number of valence electrons and have many similar characteristics.
Elements in the same group as sodium on the periodic table, such as lithium and potassium, also contain the same number of outer electrons (1) as sodium. These elements belong to Group 1 or the alkali metals group, and they share similar chemical properties due to their outer electron configuration.
No, the number of protons defines what element an atom belongs to. If two atoms are of different elements then they have different number of protons.
silicon (Si). -apex
Elements in the same column as sodium in the periodic table, such as lithium and potassium, also contain one outer electron.
The molar masses of any two elements contain the same number of moles.
