Atoms can combine to form simple molecules, such as water, or they can combine in large strings to form complex ones, such as sucrose (C 12 H 22 O 11).Because carbon has four electrons in its outer shell, it donates and accepts electrons equally well, and it's the building block of all organic molecules on which life depends. 1 Answer anor277 Sep 11, 2017 By the ... Alternatively, atoms can exchange electrons to form discrete positive and negative ions, which may be bound together in a non-molecular, electrostatic lattice. Sign in. Atoms can also combine to create materials that do not consist of discrete molecules, including crystals and liquid or solid metals. So, when two atoms combine to form molecule, energy is absorbed as well as released. Helium-4 contains 2 protons and 2 neutrons, so it requires 4 hydrogen atoms to make one helium atom. Atoms of different elements combine in simple whole numbers to form compounds. This bond is formed between two non metals. Hence, option A is the correct answer. Explanation of Solution. 1.7k LIKES. Helium-3 is created first however, adding to the complication. Latest answer posted January 20, 2016 at 10:19:45 PM Text Solution. Valence electrons. Explanation: A covalent bond is formed when an element shares its valence electron with another element. If two hydrogen atoms are initially far apart, they have identical atomic orbitals.However, as the spacing between the two atoms becomes smaller, the electron wave functions begin to overlap. Are you looking for never-ending fun in this exciting logic-brain app? The other way that atoms can combine is by something called ’fusion.’ This is when the nucleus of one atom and the nucleus of another atom actually come together, making one bigger atom with all of the electrons going around it. and one anti-bonding M.O. Arhant And Gursimar : Math Maters 2,976 views. However, a far more stable alignment of electrons arises when two hydrogen atoms share an … STUDY. Here are all the Two or more atoms combined chemically answers. 10. 7 years ago. Anonymous. Atoms have electrons on the outer shell and in this regard, atoms may not remain stable all the time. We can represent these valence electrons with Lewis diagrams. 0 1. How do atoms combine? Atoms combine together when the outermost shell, or valence shell, of electrons is not filled with two electrons (if there is only one shell) or eight electrons (if it has more than one shell). O All the atoms of an element are the same, but they are different from the atoms of other elements. Lewis diagrams for the first 20 elements are shown below. Bonding How Atoms Combine 1. Posted by krist on 26 March 2017, 4:17 pm. They stick together for pretty much the same reasons as atoms in molecules, but instead of making a little unit of fixed size, they just keep stacking up. Energy, the capacity to do work, is of two principal kinds: potential (stored) energy and kinetic energy (energy of motion). This is much less common and very hard for scientists to do. 7 years ago. 2 Educator answers. Calcium has 2 0 electrons which can be written as 2, 8, 8, 2.Thus Calcium has 2 valence electrons which it wants to give away to attain octet by having 8 electrons in its outermost orbit. Diatomic molecules. Log in or sign up first. When two atoms combine by sharing electrons, it is a covalent bond. The electrons in the outer energy level of … The copper in a wire, for example, contains many copper atoms stacked up together. - Duration: 3:43. The number of electrons in the outermost shell or orbit of an atom is ready to combine with other atoms to form a bond. Each world has more than 20 groups with 5 puzzles each. When atoms join together it is called a chemical reaction. The temperature when nitrogen and oxygen atoms combine to form NOx. O Chemical reactions occur when atoms combine, separate, or rearrange. Nitrogen and Oxygen atoms are combined when they are treated above 1600 degree Celsius... Want to see the full answer? When atoms combine together in varying numbers, molecules of different properties can be formed. they stick together for p[retty much the same reasons as atoms in molecules, but instead of making a little unit of fixed size, they just keep styacking up. The sun is made of hydrogen and helium gas, and a few trace elements that are also gas. As a team, take the set of pure substances drawings from #8 and sort them into those containing only one type of atom and those with two or more types of atoms. 3:43.
