Is density how close together atoms are

WebDensity is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold … WebHow Does Density Vary in Matter? All matter exists in three primary phases – gas, liquid and solid. The phase depends on the atoms’ energy – hot atoms have more energy, and they can move further apart (lower density); cold atoms have less energy and must stay close together (higher density).

They must be within 1x10 -15 meters of each other to fuse. The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core. WebAtoms in an FCC arrangement are packed as closely together as possible, with atoms occupying 74% of the volume. This structure is also called cubic closest packing (CCP). In CCP, there are three repeating layers of hexagonally arranged atoms. Each atom contacts six atoms in its own layer, three in the layer above, and three in the layer below. edge remove bing chat button
