Answer:
ions
Explanation:
An atom that has gained or lost an electron is called an ion. Ions are charged particles that have lost or added an electron to their outermost shell. Ions are the basis of any chemical reaction. The combination of ions leads to the formation of bonds between atoms and this results in molecules and compounds.
When atoms are in their ground state, they are otherwise neutral and such would not combine chemically. It is difficult to find elements in such form naturally. Atoms that have ionized by losing or gaining electrons would freely combine with one another in order to establish a more stable configuration.
Answer:
Kinetic energy of electron = -E₂ = 3.4 ev
Kinetic energy of electron = -E₄ = 0.85 ev
Explanation:
In case of hydrogen atom energy associated with nth state is,
En = -13.6/n²
For n = 2
E₂ = -13.6 / 2²
E₂ = -13.6/4
E₂ = -3.4 ev
Kinetic energy of electron = -E₂ = 3.4 ev
For n = 4
E₄ = -13.6 / 4²
E₄ = -13.6/16
E₄ = -0.85 ev
Kinetic energy of electron = -E₄ = 0.85 ev
A) Cl- ion
B) These energies are equal for all forms of the same element
Explanation:
The ionization energy for a chlorine atom is equal in magnitude to the electron affinity of Cl⁻ ion because these energies are equal for all forms of the same element.
- Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase.
- Ionization energy is the amount of energy required for the removal of an electron in atom or ion.
- Here the energy released when an electron is added to the Cl atom(electron affinity) to form a chlorine ion is the same energy that would be required to remove the added electron from the ion to form an atom(electronegativity).
- Here we find out that both energies are the same for the atom of Cl that is gaining electron and for the ion in which electron is being removed.

Answer:
The answer to your question is 4
Explanation:
Chemical reaction
C₂H₆ + O₂ ⇒ CO₂ + H₂O
Reactants Elements Products
2 Carbon 1
6 Hydrogen 2
2 Oxygen 3
Balanced chemical reaction
2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Reactants Elements Products
4 Carbon 4
12 Hydrogen 12
14 Oxygen 14
When the reaction is balanced the coefficient for CO₂ is 4.
If we compare a cell with an egg there is a major difference between the outer membrane
in case of cell they are bounded by semi permeable membrane
The semi permeable membrane is a selectively permeable membrane which allows the movement of only solvent molecule and not solute molecules through it.
So water can move into or out of the cell through cell membrane by a special physical process known as osmosis.
the water will move from a low concentration gradient to high concentration gradient.
