Answer:
B.The potential energy decreases while the kinetic energy increases.
Answer:
159.3 grams Al
Explanation:
1 Mol of Al = 27 grams, so:
5.9 Mol Al (27g/1mol) = 159.3 grams Al
The Mol gets canceled out, leaving the unit of grams.
Im pretty sure its A B D and E if so can you make me brainliest?
If a liquid is heated it’s particles are given more energy and will move faster, however if it is cooled, it’s particles slow down and come closer together.
Explanation:
Noble gases are group O elements and their atomic structure ensures that they are stable. All their orbitals are completely filled with electrons therefore they do not undergo reactions with other elements.
- Heavier noble gases are able to form a range of compounds due their sizes.
- Elements form compounds by exchanging or sharing of their outermost shell electrons called the valence electron.
- Every atom has specific energy required to remove electrons from them. The energy is known as the ionization energy.
- In bigger atoms which have large radius, the outermost electrons have low ionization energy which makes them easy to remove.
- The ionization energy depends on the nuclear charge, the more the charge the higher the ionization energy. Down a group the nuclear charge and ionization decreases.
- As we go down the inert group, the ionization energy of outer shell electrons become very low. This makes the electrons available to take part in chemical reactions.
