How many shells would an element from period 4 have?
I need a simple straightforward answer, not links, not answers telling me to study for myself. I am so tired and stressed out, I have been studying so hard, I can't handle it anymore. Sorry if this sounds more like a cry for help than a question, I'm desperate.
It sounds exactly like what it is. Tell me the answer. I don't want to do any work. If it isn't too much work to read this, here is the answer.
Period 1 elements have 1 shell.
Period 2 elements have 2 shells
Period 3 elements have 3 shells
Period 4 elements have 4 shells
Get it? I know it is supposed to be complicated but it's really simple.

Thank you for responding and I urge you not to get down on yourself. Everyone has a bad day now and then. Stay disciplined. If you don't understand keep asking instructors. Read more. One of the most important things to do on Jiskha is to tell us what it is that you're confused about. That tells us where to concentrate with our explanation(s). The periodic table is arranged in rows (called periods) and columns (called groups). The elements in a period have the same number of shells and the elements in groups have similar chemical properties. The maximum number of electrons in a shell is 2n^2 where n is the period number; For example, period 1 can hold no more than 2 electrons. Shell 2 can hold no more than 8 (2*2^2 = 8), period 3 can hold no more than 18 electrons (2*3^2 = 18) etc. The shells may hold fewer.than the maximum number. You're welcome to come back to Jiskha as often as you need help. But don't push us off if we direct you to a web site we think will help. Read it, then if it doesn't help come back with a follow up and tell us what is confusing to you. You'll be glad you did. Again, I urge you not to despair. Chemistry is challenging.
I understand that studying can be overwhelming at times, but please know that I'm here to help! In order to determine how many shells an element from period 4 would have, it's important to understand the periodic table and its patterns.
The period number in the periodic table corresponds to the number of electron shells an atom in that period has. Each period represents a new energy level where electrons can reside. Period 4 is the fourth row of elements on the periodic table, so elements in this period will have 4 electron shells.
I hope this answer helps alleviate some of your stress. Is there anything else I can assist you with?
