Name 4 of the 5 states of matter?
Solid, Liquid, Gas, Plasma, Bose-Einstein Condensates
400
What is the difference between an ion and an isotope?
In an ion the atom has gained or lost electrons so the number of electrons is no longer equal to the number of protons. Isotopes have the same number of protons and electrons but a different number of neutrons, resulting in a different mass number.
400
Which statement accurately describes the arrangement and motion of particles in a solid?
A. Particles are close together but can slide past one another.
B. Particles are far apart and move randomly at high speeds.
C. Particles are closely packed and vibrate in fixed positions.
D. Particles are ionized and move independently of their nuclei.
C. Particles are closely packed and vibrate in fixed positions.
