Answer:
The answer to your question is given below
Explanation:
1. When two hydrogen atoms pair together, they form a single bond to achieve complete duet.
Hydrogen atom has 1 shell and 1 valence electron and they contribute it to form bond, thereby obtaining a stable duet configuration
H + H —> H–H —> H2
2. When two halogen atom pair together, they form a single bond to achieve a complete octet which is stable. For example, Cl has 7 electrons in its outermost shell and need 1 more electron to complete it octet. Each Cl will contribute 1 electron each to form a single bond..
Cl + Cl —> Cl–Cl —>Cl2
3. When two oxygen atoms pair together, they form double bond to achieve a complete octet which is a stable configuration.
Oxygen has 6 electrons in its outermost shell and needs 2 more electrons to complete its octet configuration. Each oxygen atom will contribute 2 electrons each to form a double in order to complete it octet configuration.
O + O —> O=O —>O2
4. When two nitrogen atom pair together, they form a triple bond to achieve a complete octet which is stable. Nitrogen has 5 electrons in its outermost shell and needs 3 more electrons to complete it octet configuration. Each nitrogen atom will contribute 3 electrons each to form a triple bond in order to complete its octet configuration.
N + N —> N≡N —> N2.
Answer:
BaS + PtF2 -----> BaF2 + PtS
Explanation:
BaS + PtF2 -----> BaF2 + PtS
In the Lewis symbol for a fluorine atom, there are <u>4</u> paired and <u>1</u> unpaired electrons.
However, paired electrons simply means are 2 electrons occupying the same orbital in an atom or molecule of a substance
On the other end, unpaired electron is a single electron that occupies an orbital of an atom.
<h3>What is an atom?</h3>
An atom is the smallest part of an element which can take part in a chemical reaction.
Some atoms of elements are:
- Monoatomic
- Diatomic
- Triatomic
- Polyatomic
In conclusion, in the Lewis symbol for a fluorine atom, there are 4 paired and 1 unpaired electrons.
