Answer: When the electrons in an element are more than the required, a bond is formed with other element which has deficiency of electron and in case when electrons are less in numbers the vice versa happens. Such kind of chemical bonds are known as ionic bond.

Answer:
Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.
The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

Answer:
Explanation:
No atoms of Mg have a mass of 24.3050 u. That is the average mass of all the isotopes of Mg.
However, the most common isotope of Mg is ₁₂²⁴Mg (mass = 23.99 u)
The atomic number of Mg is 12. It has 12 protons.
The atomic mass of ²⁴Mg is 24. That's the total number of protons and neutrons.
p + n = 24
12 + n = 24
n = 12
An atom of ²⁴Mg has 12 neutrons.
If the atom is neutral, the number of electrons equals the number of protons.
e = p = 12
