The attraction of an 
ion leads to the formation of an ionic bond with 
<h3>What is an ionic bond?</h3>
Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Since the question asking among all these options:
(a) The attraction of a noble gas
(b) The attraction of a 
ion
(c) The attraction of a group 1 element
(d) The attraction of a ion
An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.
Hence, option D is correct.

Answer:you can write the definition of some main words in your experiment and the main idea of the experiment and how the experiment is to talk about.
Explanation:
Answer:
The strength of a bond depends on the amount of overlap between the two orbitals of the bonding atoms
Orbitals bond in the directions in which they protrude or point to obtain maximum overlap
Explanation:
The valence bond theory was proposed by Linus Pauling. Compounds are firmed by overlap of atomic orbitals to attain a favourable overlap integral. The better the overlap integral (extent of overlap) the better or stringer the covalent bond.
Orbitals overlap in directions which ensure a maximum overlap of atomic orbitals in the covalent bond.
Oxygen to sulfur is less polar than comparable bonds to oxygen because sulfur is less electronegative than oxygen.
In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. Fluorine is the element with the greatest electronegative charge, whereas francium has a very low electronegative charge. Within a set of elements, electronegativity values drop from top to bottom. Moving from left to right along a period improves electronegativity. This is caused by a decrease in atomic size and a rise in nuclear charge, which allows a shared electron pair to be more attracted to one another.
