Metalloids typically have electron configurations that show characteristics of both metals and nonmetals. They often have an outer shell electron configuration that is intermediate between metals and nonmetals, with some similarities to both groups. For example, metalloids like silicon and germanium have electron configurations that show both metallic properties (conductivity) and nonmetallic properties (brittleness).
No, alkali metals do not have a valence electron configuration of ns². Instead, they have a valence electron configuration of ns¹, where "n" represents the principal quantum number that corresponds to the highest energy level. This single valence electron is responsible for their characteristic properties, such as high reactivity. Alkali metals include lithium (Li), sodium (Na), potassium (K), and others, all of which share this ns¹ configuration.
Elements in the same family of the periodic table have similar bonding properties because they have the same number of valence electrons. This results in similar chemical reactivity as they tend to gain, lose, or share electrons in a similar manner to achieve a stable electron configuration. The shared valence electron configuration leads to similarities in their bonding behavior.
Metals typically share electrons by forming metallic bonds, with the electrons moving freely among the metal atoms. Nonmetals share electrons through covalent bonds, where atoms share electrons to achieve stability. Metalloids can share electrons with both metals and nonmetals, depending on the specific properties of the element.
Covalent bonds
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
Boron typically forms covalent bonds due to its electron configuration. This means that boron atoms share electrons with other atoms to achieve a stable electron configuration. Covalent bonds are formed when atoms share electrons to fill their outer electron shells and achieve a stable configuration.
Covalent compounds are most likely formed from nonmetals or a combination of nonmetals and metalloids. In these compounds, atoms share electrons to achieve a stable electron configuration. Examples of covalent compounds include water (H2O) and carbon dioxide (CO2).

Covalent bonds are typically formed between nonmetal atoms. These atoms share electron pairs to achieve a stable electron configuration.

Nonmetals share electrons through covalent bonds, where atoms share electrons to achieve stability. Metalloids can share electrons with both metals and nonmetals, depending on the specific properties of the element.
The octet rule states that atoms tend to gain, lose, or share electrons to achieve a stable electron configuration with 8 electrons in their outermost shell. Sodium has 1 electron in its outermost shell, so it tends to lose this electron to achieve a stable electron configuration, forming a sodium ion with a +1 charge.
Covalent bonds
Covalent bonds share valence electrons between atoms. In a covalent bond, the atoms involved share electron pairs to achieve a stable electron configuration.
Oxygen needs to gain two electrons to achieve a stable electron configuration, which would give it a full outer shell of eight electrons (octet). This can be achieved through forming chemical bonds with other elements.
Metalloids, such as silicon, boron, and arsenic, share characteristics with both metals and nonmetals. They have properties of both groups, such as being semi-conductive like nonmetals but also having metallic luster like metals.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
