Having studied the data for patterns and trends, you should now be able to draw some conclusions about how knowing the half-life of the element lokium would you determine the absolute age of rock in which this element is found. in a paragraph, create an imaginary example of finding a given amount of lokium and dol in a rock, and then determining the absolute age of that rock. assume that each trial represents 1,000 years.

The absolute age of that rock can be determined from the half-life of radioactive elements present in rocks such as Lokium

Further explanation

The core reaction is a reaction that causes changes in the core structure.

In the core reaction, the number of atomic numbers and mass numbers of the reactants is the same as the atomic number and mass number of the product

Radioactivity is the process of unstable isotopes towards stable isotopes by decay, by emitting certain particles, among others

• alpha α particles ₂He⁴

• beta β ₋₁e⁰ particles

• gamma particles γ

• positron particles ₁e⁰

General formulas used in decay:

$\large{\boxed{Nt=No.(\frac{1}{2}) ^{\frac{T}{t1/2} } }}$

Information:

T = duration of decay

t 1/2 = elemental half-life

N₀ = the number of initial radioactive atoms

Nt = the number of radioactive atoms left after decaying during T time

Geologists can determine the age of rocks from the content of radioactive elements in it

The procedure that can be used is to calculate the half-life using the imaginary element of the Lokium and the decaying atom called DOL (daughter of Lokium)

The procedure :

This Lokium is expressed in the form of cubes such as dice, or homemade cubesUse as many as + - 100 cubes, enter them in the boxMark this cube with a specific mark using a marker, or if the dice mark on certain numbers such as the number 1Shake the box and take the dice/cube that has been marked and facing up .This drawn dice represents DOLThen do the shaking again until you get the amount of half of the initial dice that is the remaining 50 cubes. This is called half-time

The time needed to reach this half-life is calculated from the number of shaking times, which is determined at 1000 years per shaking

This procedure can be illustrated graphically so that we know the graph that occurs whether in exponential form or not

The shaking procedure can be carried out until the cube runs out to obtain data points on the graph.

On the x-axis = the remaining cube. On the y-axis = the value of trial / shaking

From this experiment, we can find out, at what number of shaking, the half-life of Lokium was achieved

Answer from: Quest

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
