Any atom (or ion) or compound that can accept a pair of electrons to form a covalent bond.

∙ 17y agoCompounds that can accept an electron pair are known as Lewis acids. These compounds typically have an electron-deficient center, such as metals in metal ions or molecules with incomplete octets. Common examples of Lewis acids include metal ions like Al3+ and molecules like BF3.
Nonmetals burning in oxygen form covalent type compounds, as compared to metals which form ionic compounds.
These are covalent compounds.
There are four main types of organic compounds: carbohydrates, lipids, proteins, and nucleic acids. Each type plays a different role in living organisms and has unique structures and functions.
ATP belongs to the class of organic compounds known as nucleotides. Nucleotides are the building blocks of nucleic acids like DNA and RNA, and ATP is a specific type of nucleotide involved in cellular energy transfer.
A chemical reaction called a synthesis or combination reaction causes elements and compounds to join together to form new compounds. In this type of reaction, two or more reactants combine to form a single product.
Every type of atom can form compounds.
Nucleic acids and carbohydrates are types of biomolecules.
Lipids are biological compounds that contain fatty acids. These include phospholipids, triglycerides, and cholesterol esters.
At least one H+ ion, called proton, and one anion which remains when the proton is donated to a base or to a water molecule: H3O+ (hydronium) is formed, lowering pH of the water.The above isn't actually wrong, though it's worth noting that that's actually a description of a particular type of acid (an Arrhenius or possibly Brønsted-Lowry acid). Lewis acids use a more general definition and are not required to contain any particular ion... any electron pair acceptor is a Lewis acid. (All Lewis acids are Brønsted acids, but not all Brønsted acids are Lewis acids.)
These are the covalent compounds.

Amino acids form peptide bonds when bonding with one another.

The most common acids in tea are tannins, polyphenolic compounds, and caffeine. These acids contribute to the flavor profile of the tea and can vary depending on the type and processing of the tea leaves.
Helium is a noble gas and is unlikely to form molecules because it already has a full outer electron shell, making it very stable. Helium typically exists as single atoms rather than forming molecules with other elements.
