The answer is A Krypton and xenon have complete electron clouds.
The given statement is true .
<h3>What is Rutherford’s gold foil experiment?</h3>
- A piece of gold foil was hit with alpha particles, which have a favorable charge. Most alpha particles went right around. This showed that the gold particles were mostly space.
- The Rutherford gold leaf investigation supposed that most (99%) of all the mass of an atom is in the middle of the atom, that the nucleus is very small (105 times small than the length of the atom) and that is positively captured.
- For the distribution experiment, Rutherford enjoyed a metal sheet that could be as thin as practicable. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford established a gold foil for his alpha-ray scattering experimentation.

Answer: I think I’m not sure look on britanica I just asked Siri and it has to do with oxygen
Explanation:
As is, the equation has:
Reactants:
2 K
2 O
2 H
Products:
1 K
1 O
1 H
So, we can add coefficients to balance the equation:
K2O + H2O = 2KOH
The coefficient means that there are 2 moles of KOH, and now the equation is balanced as there is 2 of everything on both sides.
3 of them left and i just need points lol sorrrry
