How low or high a sound is, is determined by the frequency of sound waves. Amplitude.
"Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode."
Answer:
12 Neutrons
1 Valence Electron
23 ions [11 Protons and 12 Neutrons]
22 ions [11 Electrons and Protons]
Explanation:
To find the number of neutrons in an element, you simply take its atomic number and deduct that from the atomic mass [<em>round</em><em> </em>if necessary]. There is one <em>valence </em><em>electron</em><em> </em>because<em> </em>according to the Periodic Table of Elements, the first three energy levels can fit 2 - 8 electrons:
1st Energy Level → 2 Electrons
2nd Energy Level → 8 Electrons
3rd Energy Level → 8 Electrons
4th Energy Level → 18 Electrons
5th Energy Level → 18 Electrons
6th Energy Level [Lanthanide Series] → 32 Electrons
7th Energy Level [Actinide Series] → 32 Electrons
So, as you can see, 2 + 8 gives you 10. So from there, we already filled up 2 energy levels. Now going to the third one will leave us with only one electron left over. That is where that valence electron is.
** I encourage you to write this down in your Chemistry notebook somewhere, so you can keep this stored in your memory at all times. There are some pointers in the answer as well. Copy that.
I am joyous to assist you anytime.
Meiosis has two rounds of genetic and cellular division while Mitosis only has one. There are more complicated answers, so i dont know exactly how much info you need.
