![]() ![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'atom.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Ribosomes and spliceosomes are common examples for organelles that are not membrane-bound. Dinh, Discover Magazine, 22 July 2022 The room's reflective wall detailing and mirrored floor transports visitors to the inside of the atom. Therefore, all the elements in the periodic table are neutral atoms. As a result, the atom’s total electric charge is zero, and it is said to be neutral. For example, neon, (Ne), helium (He), iron (Fe). Examples of Neutral Atom When an atom has an equal number of electrons and protons, it has an equal number of negative (the electrons) and positive electric charges (the protons). 2022 One atom’s magnet points up, while the other points down. Most elements are atomic elements, which means that they naturally exist as single atoms, not molecules. 2023 Bottom-up synthesis builds the carbon sheets one atom at a time over a few hours. To make this happen, engineers need to know what they are working with at an. 2023 As the name implies, a nuclear thermal engine would rely on a nuclear reactor, using a process called atomic fission - in which a neutron slams into an atom to rip it apart, setting off a powerful chain reaction - to heat up propellant and provide the thrust needed to propel a rocket through space. For example, many researchers are looking beyond silicon-based computer chips to find more efficient semiconductors. If this atom loses one electron, it will become a cation with a 1+ charge (11 10 1+). 2023 When a voltage is applied to the ferroelectric, the lattice of atoms may contract or stretch, altering the mechanical properties of the material as well as its thermal conductivity. For example, a neutral sodium atom (Z 11) has 11 electrons. Tim Newcomb, Popular Mechanics, 22 Feb. For example, carbon atoms have six protons, hydrogen atoms have one and oxygen atoms have eight. 2023 In one theory, a Big Bang event billions of years ago created a universe so new that atoms weren’t even a reality. 2023 In each form, its atoms occupy a very different volume than the preceding one. Recent Examples on the Web The reactor, known as a fast breeder, excels at making plutonium, a top fuel of atom bombs. (b) the positively charged parts of atoms are moving about with a velocity approaching the. ![]()
