i need help, I'm studying for my chemistry final i don't wanna fail plz help
It is in the "Normal state" AKA "ground state" . When one or more electrons goes to higher energy states by acquiring energy, then it is called "Excited State".
Ground state
Ground State
lowest energy band (where n=0)
There are 88 protons/electrons in radium. There are 138 neutrons.

There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
Electrons differ in the amount of energy they have and how tightly they are held by the protons in the nucleus. Based on these properties, chemists describe an atom's electrons as belonging to certain energy levels. Usually it is the electrons in the highest energy level of an atom that determine how that atom reacts.
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
Same amount as the Proton count - 18
A potassium atom has 19 protons.An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.
An electron in the third shell has more energy than an electron in the second shell.
The amount of electrons is Argon is 18.
yes
You did not describe the amount of potassium bicarbonate amount in grams in your question. But if you are about 1 gram of potassium bicarbonate it will be 0.0099 moles in one gram of potassium bicarbonate. 0.0199 moles in 2 grams of potassium bicarbonate.
No, they have the same amount of potassium either way.
Potassium 40 is an isotope with 19 protons (and electrons) and 21 neutrons. Potassium 40 accounts for around 0.012% of potassium and is fairly stable (half life of 1.25 billion years).Potassium 40 is an isotope with 19 protons (and electrons) and 21 neutrons.

Not usually. Potassium iodide is usually present in a large excess. It is usually the potassium iodate that is the limiting ingredient.
its depends in the amount of potassium chloride.
Argon has 10 core electrons. Subtract the amount of valence electrons from your total amount of electrons. 18-8= 10
