The electronic configuration of a ground-state Cr-atom :
1s²2s²2p⁶3s²3p⁶4s²3d⁴
<h3><u>What are electronic configurations?</u></h3>
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.

Option c would be the correct answer
Answer: The correct answer is 1%: exponential decay.
Explanation: We are given a function:
...(1)
To determine the percentage rate of change in function, we compare the given function with the general form of exponent function, which is:
...(2)
Comparing both the equations, we get:


We take 'r' in percentage, so converting this above value in percentage, we get:

As the value of 'r' is negative, it means that the exponent is decaying, so the percentage rate of change in function will be 1% and it will be exponential decay.
Answer:
RbOH
Explanation:
For this question, we have to remember what is the definition of a base. A base is a compound that has the <u>ability to produce hydroxyl ions</u>
, so:

With this in mind we can write the <u>reaction for each substance:</u>




The only compound that fits with the definition is
, so this is our <u>base</u>.
I hope it helps!
