Answer:
Electronic configuration of nitrogen: K=2 L=5
Electronic configuration of phosphorus : K = 2 L = 8 M = 5
The element nitrogen will be more electronegative because of the smaller size of its atom. nitrogen accepts electrons more easily.
Explanation:
Using electronegativity difference is a good guide to the ionic/ covalent nature. Large differences indicate greater ionic character, small differences more covalent character. The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have.
Ionic bonding is formed through electrostatic attraction between a cation and anion. Foe example, Sodium fluoride has ionic bonding because it is composed by sodium and Fluorine (a non metal). On the other hand, covalent bonding is characterized by atoms sharing pairs of electrons. For example; methane has covalent bonding; carbon has 4 valence electrons and hydrogen has 1; when they bond they have a total of 8 electrons and satisfies the octet rule.
Answer:
2. Volcanoes
Explanation:
The interior of some planets (e.g earth) contains some hot flowing fluids called lava which has a very high thermal energy. The lava as a means of escaping the confinement within the planet, burst out by creating an opening through the ground to the surface of the planet to release the energy (lava).
This process in which the energy is released to the surface of the planet is termed volcanic eruptions. Which occurs majorly in some susceptible regions of the earth.
The openings in the ground that release energy from deep inside the planet is thus called volcanoes.
Answer: 100 times
Explanation: Since logaritms are about exponent of base ten.The concentration will be 10^2 or 100 times greater concentration.
