He Helium is a noble gas
The noble gas configuration of oxygen (O) is [He] 2s^2 2p^4, where [He] represents the electron configuration of the nearest noble gas, helium.
Yes it is possible to write the noble gas configuration of all elements, though it is not possible to list all of them here.
The reaction represented by H₂O → H₂(g) + O₂(g) is a decomposition reaction. In this reaction, water (H₂O) is broken down into its constituent elements, hydrogen gas (H₂) and oxygen gas (O₂), typically through the process of electrolysis or thermolysis. Decomposition reactions involve the separation of a compound into simpler substances.
The elements are Carbon (C) Hydrogen(H) Oxygen(O)
O H
Lemonade primarily consists of water (H₂O) and citric acid (C₆H₈O₇), which are made up of the elements hydrogen (H), oxygen (O), and carbon (C). Additionally, if you add sugar, sucrose (C₁₂H₂₂O₁₁) introduces more carbon (C), hydrogen (H), and oxygen (O) elements. Depending on the recipe, other elements may come from added flavors or preservatives, but the main components are these three elements.
Neon (Ne) is unlikely to be in a covalent molecule because it is a noble gas and typically exists as single atoms due to its stable electron configuration. The other elements listed (H, B, C, N, O, and F) commonly form covalent molecules because they do not readily lose or gain electrons to form ionic bonds.
H O
It is in Group O or Group 8. Also known as noble gas, they do not react with other elements as they do not have to react to get a stable configuration.
The principal elements are C, H, O.
These elements are C, H, O.
Three different elements: C, H, O. 3 C-atoms 8 H-atoms 10 (=3*2+4) O-atoms
