Ii is definitely true!
False. An alpha particle is equivalent to a helium-4 nucleus.
false
It is false.
False elements are made up of atomsFalse.
False. Gamma rays are electromagnetic radiation, not particles with charge. They are produced by the decay of atomic nuclei or during high-energy interactions.
false
False. Particles do not have a fixed size, as their size can vary depending on the type of particle and its environment. At the quantum level, particles can exhibit wave-particle duality, meaning they can behave both as particles and waves with differing characteristics.
False. Sand is not the smallest particle; it is categorized as a granular material with larger particle sizes compared to silt and clay. While sand particles can stick together due to moisture or adhesive properties, they are not as cohesive as finer particles like clay.
True. The strength of the electric field created by a charged particle is inversely proportional to the square of the distance from the particle. As the distance decreases, the electric field strength increases.
False. Ions are formed from the loss or gain of electrons by atoms, resulting in a charged particle. Covalent bonding involves the sharing of electrons between atoms.
