Well who knows what coud be in the future?the houses could be floating in the future. the cars coud run on solar energy.
so im here to tell you about the future and houses and cars.
B). Visible Light. Hope that helps
Answer:
phosphorus sulfide should be P2S3
Explanation:
Phosphorus can't exists as an atom itself, it needs to be like oxygen, so it must have 2 atoms covalently bonded to each others, making it P2. Sulfide itself is sulphur bonded in a 3 way exchange. Sulphate is the 2 way exchange, so S3 would be attached to phosphorus, making it P2S3
First let us identify its ground state configuration.
[Xe]6s1
The inner electron is the number of electron 54 (in Xe).
Inner electrons: 54
The valence electron and outer electron in this one is the same because it is in 6s. 1.
Outer electrons: 1
Valence electrons: 1
<h3>What is valence electron?</h3>
- A valence electron is an electron that is part of an atom's outer shell in chemistry and physics.
- If the outer shell is open, the valence electron can take part in the formation of a chemical bond.
- Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
- The chemical properties of an element, such as its valence—whether it can connect with other elements and, if so, how quickly and with how many—may be affected by the existence of valence electrons.
- In this approach, the electrical arrangement of an element greatly influences its reactivity.
<h3>What is electron?</h3>
- The elementary charge, commonly known as the electric charge, has an electric charge of 1.602176634 coulombs, which is used as a standard unit of charge for subatomic particles.
- The electron charge is identical to the proton charge, within the limits of experimental precision, but with the opposite sign.
