WebMar 19, 2010 · At least two atoms are needed to make a molecule, such as in oxygen gas, [math]O_ {2} [/math], which has two oxygen atoms. But, that is just a lower bound, as molecules can be much larger and contain many more atoms that just 2. 6 3 Lawrence C. FinTech Enthusiast, Expert Investor, Finance at Masterworks Updated Feb 6 Promoted WebAtoms are different from each other because the numbers of the subatomic particles are different. -To measure the overall charge, count up the positive atoms and the negative atoms and add those together. -As long as the number of protons and electrons are equal, the atom is without charge, or neutral. -Atomic number is the same thing as a proton.

WebCollision theory explains why most reaction rates increase as concentrations increase. With an increase in the concentration of any reacting substance, the chances for collisions between molecules are increased because there are more molecules per unit of volume. WebOct 13, 2024 · Polymer chains can include hundreds of thousands of atoms — even millions. The longer a polymer chain, the heavier it will be. And, in general, longer polymers will give the materials made from them a higher melting and boiling temperature. Also, the longer a polymer chain, the higher its viscosity (or resistance to flow as a liquid). how to sell your tickets online

WebDown the groups, atomic radius increases. This is because there are more energy levels and therefore a greater distance between protons and electrons. In addition, electron shielding causes attraction to decrease, so remaining electrons can go farther away from the positively charged nucleus. Therefore, the size, or atomic radius, increases. WebAs you go down the Group, the atomic radius increases, and so the volume of the atoms increases as well. That means that you can't pack as many sodium atoms into a given volume as you can lithium atoms. However, as you go down the Group, the mass of the atoms increases.
