What can we say about graph 3 using the Atomic numbers of nitrogen, oxygen, neon, calcium, scandium, titanium, vanadium, chromium and magnesium? And boiling points of -195.8 to 2061
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn 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, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
As the atomic number increases, the number of unpaired electrons also increases in case of d-block elements from scandium to cromium(left to right). So metallic bonds between these atoms are very strong and require greater amount of energy to break these bonds. So they have higher boiling point.
The boiling points increase because the number of electrons increases, as does the radius of the atom. The greater the number of electrons and the greater the distance over which they can move, the greater the possibility of temporary dipoles and, consequently, the greater the dispersion forces.
