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

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:

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 :

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

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
