One atom that is a highly reactive element can take on 7 more electrons but has fewer protons than sodium?
Lithium is the answer. It has fewer protons than sodium (Na) and has room for 7 electrons. You can figure this out by using the formula 2n^2, where n is the valence shell. For instance, He (helium) only has one valence shell, so 2*1^2 = 2. He has 2 electrons, so it's shell is full, which is why it is stable, and a noble gas. Lithium however has two valence shells and 3 electrons. So, using our formula we can see that 2*2^2 = 8. So we always fill in the first shell first, so the first two electrons go in the first valence shell, and then the second valence shell gets the last electron. But wait, the 2nd valence shell can hold up to 8 electrons, so there's room for 7 more in the shell.

What is the reactivity of the element chlorine?
Chlorine is highly reactive because it readily accepts electrons to achieve a stable electron configuration. It can react with a wide range of elements and compounds to form various products, including chlorides.
Which is more reactive fluorine or nitrogen?
Fluorine is the most reactive element period. So, it is therefore more reactive than carbon. However, as carbon forms the basis of organic molecules, people come across its compounds more often.
Is Sodium a period 3 element that is highly reactive?
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.

It might be because, if the number of electrons are diminished then the number of protons might make the element a highly positively charged element (positive ion)!
Is plutonium highly reactive are non reactive?
Plutonium is not highly reactive under normal conditions. It is a relatively stable element that does not react readily with air or water. However, it can be reactive in certain chemical reactions or when exposed to high-energy particles.
