D. level of the water table
hope its helps
<span>"too much water can cause raging floods and flush pollutants and soil into rivers and streams"
</span>the statement i got the answer from
<h3>Answer:</h3>
Strontium (Sr)
<h3>Explanation:</h3>
The condition given in statement is the presence of two valence electron. Hence, first we found the electronic configuration of given atoms as follow;
Rubidium [Kr] 5s¹
Strontium [Kr] 5s²
Zirconium [Kr] 4d² 5s²
Silver [Kr] 4d¹⁰ 5s¹
From above configurations it is cleared that only Strontium and Zirconium has two electrons in its valence shell.
We also know that s-block elements are more reactive than transition elements due to less shielding effect in transition elements hence, making it difficult for transition metals to loose electrons as compared to s-block elements. Therefore, we can conclude that Strontium present in s-block with two valence electrons is the correct answer.
I think the answer is covalent bonds.
Answer:
a. the electrons shared between the oxygen and hydrogen atoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus.
Explanation:
Water molecule is a polar molecule , and hence , the atom can attain the respective partial positive and negative charge on them .
The difference in the electronegativity gives rise to the partial positive and negative charge .
Since , oxygen atom is more electronegative in comparison to hydrogen atom , and hence , slightly pulls the electrons towards itself , and attains partial negative charge , and correspondingly , the hydrogen atom attains partial positive charge .
Hence , from the question ,
The correct option is a.
Answer is: D- there are different elements as products.
In balanced chemical reaction, there are same elements and number of elements on both sides of the reaction.
In nuclear reaction there are different elements and number of elements on the nuclear reaction.
For example nuclear reactions are alpha and beta decay, where new elements have different atomic and mass number.
