Write a nuclear equation for the decay of Polonium 211

Chemistry
1 answer:
kumpel [21]3 years ago
3 0

Answer:

₈₄Po²¹¹   →   ₈₂Pb²⁰⁷  + ₂He⁴  + energy

Explanation:

Polonium-211 is unstable nuclei. It undergoes alpha decay and produce Pb-207 and alpha particle.

Nuclear equation:

₈₄Po²¹¹   →   ₈₂Pb²⁰⁷  + ₂He⁴  + energy

Properties of alpha radiation:

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4  and atomic number less than 2 as compared to parent atom the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

Determine the percentage composition of Ptl2
Hitman42 [59]

Answer:

Percent Composition

1. Find the molar mass of all the elements in the compound in grams per mole.

2. Find the molecular mass of the entire compound.

3. Divide the component's molar mass by the entire molecular mass.

4. You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

For Row 2 according to the respective Column is

  • Mn, 25, 55, 25, 25,30, 3-

For Row 3 according to the respective Column is

  • P, 15, 31, 15 ,15 ,16 ,0

For Row 4 according to the respective Column is

  • O^{2-} , 8 ,16 ,8 ,6 ,8 , 2-

For Row 5 according to the respective Column is

  • Na, 11, 23, 11, 10, 12, 1-

From the question we are told

Ions, isotope, average atomic mass fill in the blank

Generally

Where

  • Z signifies the Proton Number of the atom
  • A signifies Mass Number of the atom

Therefore

For Row 1 according to the respective Column is

  • Zn^{2+} , 32 ,65 ,32 ,30 ,34 ,2+

For Row 2 according to the respective Column is

  • Mn, 25, 55, 25, 25,30, 3-

For Row 3 according to the respective Column is

  • P, 15, 31, 15 ,15 ,16 ,0

For Row 4 according to the respective Column is

  • O^{2-} , 8 ,16 ,8 ,6 ,8 , 2-

For Row 5 according to the respective Column is

  • Na, 11, 23, 11, 10, 12, 1-

Look at the equation for a displacement reaction below. What lost electrons in the reaction? Give the full name, not the symbols
garri49 [273]

Answer:

Cupric ions

Explanation:

In the single displacement reaction shown, the cupric ions lost two electrons.

    Cu²⁺  + 2e⁻ →  Cu

The replacement of a metallic ion in solution by a metal atom higher in the activity series than than the metal in solution falls into this category of reactions.

  Since Zn higher in the series, it displacements the cupric ions.
