WebWhen two or more atoms of different elements join together, we call it a compound. All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of … WebWhen two atoms of the same chemical element bond together they form a diatonic molecule. When two atoms of different chemical elements bond, they form a chemical compound. Atoms are held together because there is an electrostatic attractive force between the two atoms. Energy is required for the chemical reaction to bond atoms.

WebEach element is designated by its chemical symbol, which is a single capital letter or, when the first letter is already “taken” by another element, a combination of two letters. Some elements follow the English term for the element, such as C for carbon and Ca for calcium. And how the electrons of other elements are configured. Or maybe, other atoms of … WebThe more a atom wants an electron, the more electronegative it is and visa versa. To imagine whats more electronegative, simply look at the periodic table. At the far bottom left to the top right is the scale for how electronegative an atom is. The closer to the bottom left, the less an atom is electronegative. WebOct 1, 2024 · Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale.
