Explanation:
Answer:
matter is anything that has mass and takes up space so it could be heavy light small or big
Explanation:
whatever describes mass and space
As bond number increases (double bonds rather than single, triple rather than double etc. ), bond length decreases and bond energy increases
Reason-Charges that are spaced apart are described by a dipole moment. There are two critical criteria that must be taken into account when assessing if a molecule has a dipole moment. It must first possess polar covalent bonds. The individual dipoles must not cancel out in the molecular structure, which is the second requirement. Because Br2 is not a polar molecule, it lacks a polar covalent bond.A bond number is a simple addition of two numbers that total the sum. Using number bonds, one can quickly determine the answer without performing any calculations. We can see from the example that when we see a number bond, we know the answer without having to calculate.

what are electrons ?
The electron is a subatomic particle with an initial electric charge of -1. Electrons are the first generation of the lepton particle family and are often regarded as elementary particles due to the lack of known components or substructure. The mass of an electron is roughly 1/1836 that of a proton. The electron's quantum mechanical characteristics include a half-integer intrinsic angular momentum (spin) given in units of the decreased Planck constant, Because electrons are fermions, they cannot inhabit the same quantum state, according to the Pauli exclusion principle. Electrons, like other elementary particles, have both particle and wave properties: they may collide with other particles and be diffracted like light.
Because electrons have a smaller mass and hence a longer de Broglie wavelength for a given energy, their wave characteristics are simpler to examine with experiments than those of other particles such as neutrons and protons.
