please do give me brainliest if this helped you.
thank you and have a great day :D
Answer:
Potassium (K) has a larger average atomic radius (220 pm) than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius. The ionic radius increases in a particular group on moving from top to bottom due to increase in the principle energy shell though the number or electrons in the valence shell remain the same
This is too hard to answer
Answer:
Explanation:
The reaction we need to calculate:
1) 
We need the ClO in the products side, so we use the inverse of this reaction:
2) 
Now we need to combine this two:
The enthalpy of reaction:
The number of protons is equal to their atomic number ever time.
For example: Carbon always has 6 protons
And the number of neutrons depends on whether it is Carbon 12 or 13 or 14 etc.
