Answer:
Here's what I get
Explanation:
An orbital is a region in space where an orbital is most likely to be found. It has a specific size, shape, and energy level, depending on its set of quantum numbers.
For example, the order of increasing orbital energies is n = 1, 2, 3, …. Orbitals with the same principal quantum number (n) belong to the same energy level.
Orbitals in energy levels with n > 1 can be divided into groups depending on their secondary quantum number (l).
For example, the n=3 energy level consists of 10 orbitals — one s, three p, and five d orbitals. the s, p, and d orbitals constitute three sublevels with slightly different energies in the n = 3 energy level.
1978 to 2004 is <em>26 years</em>.
Every 5.23 years, half of our 200-gram sample decays.
It has reached its half life ~4.97 times.
We use this formula to find our new amount:
Every time it reaches its half life, it will be halved...the fractional exponent there is to pick up minute differences like in our 4.97.
The balanced chemical reaction of potassium chloride involves 2 moles of potassium to react with 1 mole of chlorine and other are explained below.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equations in which all entities are present in same amount on reactant as well as on the product side of the reaction.
Given chemical reactions are:
- First equation is a balanced equation in which nitrogen reacts with hydrogen to form ammonia because all are present in same quantity on both sides.
- Second equation is not a balances equation as number of chlorine atoms are not present in same quantity, so balanced equation is:
2K + Cl₂ → 2KCl
- Balanced equation for the third reaction is:
CF₄ + 2Br₂ → CBr₄ + 2F₂
- Balanced equation for the fourth reaction is:
GaF₃ + 3Cs → 3CsF + Ga
- Fifth reaction between barium sulfide and platinum di fluoride is balanced as all atoms are present in same amount on both sides.
- Balanced equation for the last reaction is:
MgF₂ + Li₂CO₃ → MgCO₃ + 2LiF
Hence in the formation of potassium chloride balanced equation involves 2 moles of potassium to react with 1 mole of chlorine.

Answer:
⁹⁶₄₂Mo + ²₁H ⇒ ⁹⁸₄₃Tc
Explanation:
During the bombardment of a molybdenum target with deuterium ions, an element not found in nature was produced.The name of the element formed in the process is technetium. It is an element with the symbol Tc, mass number of 98, and atomic number 43. The nuclear equation is shown below:
⁹⁶₄₂Mo + ²₁H ⇒ ⁹⁸₄₃Tc
Technetium is the lightest element whose isotopes are all radioactive in nature except the fully ionized state of isotope ⁹⁷Tc. It is silvery gray in color and can be found between manganese and rhenium in group seven of the periodic table.
