Write the identity of the missing nucleus for the following nuclear decay reaction: 18 9f→01e+?

This element X is an isotope of element O

The core reaction:

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

Known variable

Core reaction

Asked

Complete the reaction

Answer

The ₉F¹⁸ element is radioactive, so to achieve stability it emits positron ₊₁e⁰ particle which produces a stable ₈X¹⁸ element

Core reactions that occur:

If we see an atomic number of 8 and we see it in a periodic system, this element X is an element of O

The number of mass O itself can change, it can be worth 16.17, or 18 because element O has an isotope

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
