The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explain…

Shape of the D Orbital

Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.

(b) substances

(d) a substance composed of two or more elements combined in deï¬�nite proportions

(e) a combination of atoms of one or more elements

(f) a process Characterized by Changes only in ï¬�le physical properties of a substance not in its composition

(g) the physical state in which matter has no ï¬�xed shape or volume but expands to ï¬�ll its container completely

(h) ï¬�le energy possessed by an object because of its position

(i) a tentative explanation for the properties or behaviour of matter that accounts for a set of observations and can be tested

(j) the energy possessed by an object because of its motion

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
