Answer:
Se =[Ar] 3d¹⁰ 4s² 4p⁴
Explanation:
The noble gas notation is used for the shortest electronic configuration of other periodic table elements.
For example:
The atomic number of Argon is 18, and its electronic configuration is,
Ar₁₈ = 1s² 2s² 2p⁶ 3s² 3p⁶
The atomic number of selenium is 34, its electronic configuration is,
Se₃₄ = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁴
By using the noble gas notation, electronic configuration of selenium can be written is shortest form.
Se =[Ar] 3d¹⁰ 4s² 4p⁴
This electronic configuration is also called abbreviated electronic configuration.
Answer:
571.81 mL
Explanation:
Assuming constant pressure, we can solve this problem by using <em>Charles' law</em>, which states that at constant pressure:
Where in this case:
We <u>input the data</u>:
- 852 mL * 200 K = V₂ * 298 K
And <u>solve for V₂</u>:
The new volume would be 571.81 mL.
ion, proton
Explanation:
Ions and protons have profound relationships.
An ion is an atom that has lost or gained electrons.
A proton is a positively charged subatomic particle.
What is the relationship between an ion and a proton?
- In an atom, there are three fundamental particles.
- Protons are the positively charged particles located in the nucleus of atoms.
- Electrons are the negatively charged particles orbiting round an atom.
- Neutrons have no charges and they occupy the nucleus with protons.
Atoms are electrically neutral and this implies that they have equal number of protons and electrons.
In an ion, the number of protons and electrons differ.
For positive charged ions, the number of protons is more suggesting they have lost electrons.
For negatively charged ions. the number of protons is less suggesting they must have added electrons.
Compound are combinations of different atoms.
