Yes, in a heterogeneous mixture, the different substances are not uniformly distributed and can often be visually distinguished. They can usually be separated by physical means such as filtering, settling, or using a magnet.
Substances that do not follow the particle model are usually those at extremely high temperatures and pressures, such as in plasma or certain quantum states, where the traditional concept of particles breaks down. Additionally, phenomena like quantum entanglement and certain aspects of dark matter and energy challenge the classical particle model.
A hydrogen ion, when in reaction, usually donates its core which essentially is a proton that attracts negative charges, which in turn makes the positively charged hydrogen ion an electrophile.
A nucleus with more than 82 protons is usually unstable and may emit alpha or beta radiation to become more stable. This process helps lower the number of protons and neutrons in the nucleus, bringing it closer to a more stable configuration.
Germanium has been said by many to be a metal, but it is only carrying characteristics of a metal so it can be called a semi-metal. Despite this Germanium is most usually classed as a metalloid.
The specimen is usually the glass particle in the serum separator tubes.
For rectangles, the longest sides are always the 'length' measurement.
Longest
The boson particle is usually associated with the Higgs field. It is an energy field that transmits the mass to the things that travel through it.
A particle filter is usually used in statistics to estimate Bayesian models. a particle filter is also known as a sequential Monte Carlo method (SMC).
neutrones
The femur - a leg bone - is usually the longest bone in the human body.
No, it is an element - a type of atom. The positive hydrogen ion, on the other hand, is usually identical with the proton, which is a subatomic particle.
It is usually, but not necessarily, its longest dimension.
The one in the middle, (usually) the longest
An atom is the smallest particle of an element that has the properties of that element. The atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element. No Sub-Atomic Particles have any characterisitics of an element. It is the collective arrangement of electrons and protons (and usually neutrons) which gives an element its characteristics. An atom is the smallest particle that has elemental characteristics.
The charge ratio of a proton to an alpha particle is 1:2. An alpha particle is merely a helium nucleus, composed of exactly two protons and usually two neutrons.
