Answer : A single carbon atom can form a maximum of <u>Four (4)</u> covalent bond(s).
Explanation : A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.
Formation of covalent bond depends on the number of valence electrons. Electronic configuration of Carbon (C) is :
Valence electronic configuration of C is :
Carbon have four valence electron that means Carbon can form maximum of four covalent bonds.
For example : In methane (CH4) Cabon can share four electrons with four Hydrogen atoms and can form four covalent bonds with 4 H.
The Chlorine and fluorine atoms are the most electronegative.
So, option D and E is correct one.
The atom of a given chemical elements having tendency to attract bonded pair of electron toward itself is called electronegativity. The electronegativity of atoms is affected by both its atomic number and distance at which its valence electrons resides from the charged nucleus.
The electronegativity of the elements is increases on moving left to right in the period of periodic table while decreasing on moving top to bottom in the group of periodic table .
Example:
The elctronegativity of fluorine atom = 3.98
The elctronegativity of chlorine atom =3.16
The elctronegativity of carbon atom = 2.25
The elctronegativity of phosphorus atom = 2.19
The elctronegativity of silicon atom = 2.58

Answer:
proton
Explanation:
The atoms is made from a nucleus and a electronic shell. The nucleus is composed from protons (positively charged) and neutrons (no charge). The electronic shell is defined by the presence of electrons (negativity charged).
Now a particular element is identified by the number of protons which have to be equal to the number of electrons in the electronic shell. A particular element may have the same number of protons but different number of neutrons, these are isotopes which have the same chemical properties.

The path taken by pollen as it fertilizes a plant would be:
anther ---> stigma ---> style ---> ovule
The fertilization process in plant starts by pollination. Pollen grains move from the anther of a flower to the stigma of the same or different flower. On the stigma, the pollen germinates and the cells of the pollen tube grows through the style to reach the ovule.
The generative cell of the pollen travel through the pollen tube to reach the embryo sac of the ovule. The cell divides by mitosis to form sperm cells and one of the sperm cells fertilizes the egg cell to form the zygote.
