Nuclear i believe because it has nucleus in the sentence and also talk about it
<u>Answer</u>:
This describes primary succession.
<u>Explanation</u>:
In the case of primary succession, the sequence of communities is formed in lifeless habitat. With the formation of the new ecosystem, life evolves gradually. In retreating glacier’s case, the new land is being revealed on its receding.
During the initial stage, the land is void of soil and vegetation. This leads to micro-organisms to breakdown the bedrock and soil formation starts. With the efficient amount of soil creation the new vegetation starts.
Answer:
Chemical (you should mark me brainliest lol)
Explanation:
Chemical properties can only be measured by changing substances chemical identity.
First let us identify its ground state configuration.
[Xe]6s1
The inner electron is the number of electron 54 (in Xe).
Inner electrons: 54
The valence electron and outer electron in this one is the same because it is in 6s. 1.
Outer electrons: 1
Valence electrons: 1
<h3>What is valence electron?</h3>
- A valence electron is an electron that is part of an atom's outer shell in chemistry and physics.
- If the outer shell is open, the valence electron can take part in the formation of a chemical bond.
- Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
- The chemical properties of an element, such as its valence—whether it can connect with other elements and, if so, how quickly and with how many—may be affected by the existence of valence electrons.
- In this approach, the electrical arrangement of an element greatly influences its reactivity.
<h3>What is electron?</h3>
- The elementary charge, commonly known as the electric charge, has an electric charge of 1.602176634 coulombs, which is used as a standard unit of charge for subatomic particles.
- The electron charge is identical to the proton charge, within the limits of experimental precision, but with the opposite sign.
