Answer:
a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits.
Explanation:
Answer:
The coordination number.
Explanation:
The coordination number is defined as the number of atoms surrounding an atom in a crystal lattice and indicates how tightly the atoms are packed together.
Coordination number is also known as ligancy in chemistry and it basically refers to the total or overall number of neighboring ions, atoms or molecules with respect to a central atom in a crystal lattice. The term coordination number was first defined by the notable and amiable Swiss chemist by the name, Alfred Werner in 1893.
Generally, the coordination number of an atom in a crystal lattice can have a minimum value of two (2) and a maximum value of sixteen (16). It is usually determined by the size of the ligands, central atom and the charge associated with the electronic configuration of an ion. For example, the coordination number of carbon in methane (CH4) is four (4) because an atom of carbon has four (4) atoms of hydrogen bonded to it.
Answer:
2-0-1, 1-1-1, 0-1-2, but they must all equal 3 electrons in total
Explanation:
Answer:
The concentration of chloride ion is 2.887 M.
Explanation:
Here we have a combination BaCl₂ and AlCl₃
1 mole BaCl₂ can produce 2 moles chloride ions as follows;
BaCl₂ → Ba²⁺ + 2Cl⁻
Therefore;
0.554 mole BaCl₂ can produce 2×0.554 moles chloride ions;
1 mole AlCl₃ can produce 3 moles chloride ions as follows;
AlCl₃ → Al³⁺ + 3Cl⁻
Therefore;
0.593 mole AlCl₃ can produce 3×0.593 moles chloride ions
Total concentration of chloride ions = 2×0.554 + 3×0.593 = 2.887 moles of Cl⁻ in 2×16.8 ml solution
The concentration of Cl⁻ is 2.887 M
Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .
<h3>What do you mean by the nuclear fusion ?</h3>
Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
The main advantage of nuclear fusion is it is safe source for the generation of electricity.
Characteristics of nuclear fusion -:
- The main characteristic of nuclear fusion is that it involves formation of a singular particle from two or more atoms.
- Unlike nuclear fission, nuclear fusion is common in nature- just hard to recreate.
- Nuclear fusion typically produces few radioactive particles .
- Fusion works by applying a great deal of pressure to overcome .
Hence ,Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .
