<u>Thorium series</u> could start by this sequence.

<h3>Brief explanation</h3>

To write balanced equations for nuclear decay processes. It's important to remember that the mass number and the atomic numbers must be balanced. And so what that means is that if we look at an elements nuclear symbol, the atomic number is the bottom number and the top number, the superscript, is the mass number, and so when we add them up on both sides, they have to be equal. There are two different ways in which decay can occur.

In this, series one is through beta decay, which means that the following particle is produced. The other is Alpha Decay, which produces this particle. Both are products. So if we start off with uranium to 39 you read it in nuclear notation, which means we have to find the atomic number just 92 and it undergoes beta decay.

So that means that it produces this particle find the second particle we used the atomic number, so 92 equals minus one plus x, where X equals 93 which is Neptune IAM. The mass number of our new isotope is zero plus X equals to 39 where X equals to 39. This product becomes the reactant in my next decay, which is also a beta decay. And to find the unknown element we do the same here.

Except for that it's 93 equals minus one plus x, where X is 94 which is P u plutonium, and the mass number is zero plus X equals to 39 or to 39. The next decay starts with the isotope that we just form to 39 p. U. This time it's an Alpha decay. So we produce this particle to find the unknown. Element 94 equals two plus x, where X equals 92 which takes us back to uranium.

Find the mass number of this isotope 2 39 equals four plus X, where X equals to 35. Finally, for the last decay, you have another Alpha decay starting with uranium to 35 making an alpha particle. The atomic number will be 90 which is T H and the top is 2 31 For the mass number. This begins the natural decay, series of thorium .

Choose the element described by the following electron configuration.
nadezda [96]

Answer:

The answer to your question is Argon

Explanation:

Electron configuration given               1s² 2s² 2p⁶ 3s² 3p⁶

To find the element whose electron configuration is given, we can do it by two methods.

Number 1. Sum all the exponents the result will give you the atomic number of the element.

                      2 + 2 + 6 + 2 + 6 = 18

The element with an atomic number of 18 is Argon.

Number 2. Look at the last terms of the electronic configuration

                      3s² 3p⁶

Number three indicates that this element is in the third period in the periodic table.

Sum the exponents    2 + 6 = 8

Number 8 indicates that this element is the number 8 of that period without considering the transition elements.

The element with these characteristics is Argon.
