Noble gases are found in Group ____ of the Periodic Table.
Group 18 :)
Noble gas atoms are…
- stable
- unreactive (inert)
Noble gases exist in nature as ____________ .
single atoms 🙎😩
Noble gases have ____ valence shells.
full / complete
Ions are formed when…
an atom loses or gains electrons
Atoms with a nearly empty valence shell will…
lose electrons 😓
Positively charged ions are also called…
CATIONS
😼meoww
When electrons are lost, they form…
positively charged ions (cations)
Atoms with a nearly full valence shell will…
gain electrons 💪😄
Negatively charged ions are also called…
ANIONS
🧅 yumm?
When electrons are gained, they form…
negatively charged ions (anions)
When writing chemical formula of cations, what is the charge written on the top right corner?
+
yea thats it…unfortunately no emojis 🫣 SIIIKE

number of protons = _____
number of electrons 💫
Cation –> proton __ electron
proton > electron
Anion –> proton __ electron
proton < electron

you get what i mean, right?
