Answer:
Option C is correct = fluorine
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
This diagram show that there are 9 electrons and 9 protons are present. We know that the number of protons or electrons are atomic number of that element. From periodic table we know that atomic number of fluorine is 9 thus the given atom present fluorine atom.
Another name for a mesh screen is a sieve.
To estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.
<h3>What is a dimension?</h3>
Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.
Dimensional measurement is of fundamental importance for interchangeability and global trade.
Hence, to estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.

Ionic bonding would be the answer because they transfer electrons. This gives them a charge. If it loses electrons, it becomes an cation, with a positive charge. While if they gain an electron, they get a negative charge, and become a anion. Transferring an electron is losing or gaining, therefore your answer would be that since electrons are permanently being transferred, the answer is IONIC BOND.
Covalent bonds is a wrong answer because they share electrons, which gives them no charge (neutral).
Also, metallic bonding is not the correct answer.
So our final answer: A- Ionic bond
It takes into account the different molecular masses of the different chemicals by providing a fixed and standardised number of molecules/ atoms for chemicals to be measured
