Answer:
All of the 3s orbitals on all of the atoms overlap to give a vast number of molecular orbitals which extend over the whole piece of metal. The electrons can move freely within these molecular orbitals, and so each electron becomes detached from its parent atom. The electrons are said to be delocalized.
Explanation:
I hope you understand
a) ionic
chlorine is present in top of group 17 and right of period 3 and
electronegativity(the tendency to gain electrons)
increases up the group and right the group.
so it has high tendency to form anion.
In the same way both Na and K are present up the group and left side and the tendency to lose electrons in both becomes high and they tend to form cation.
Solubility at 100 °C = 480 g / 100 mL of solution =: saturated solution
The proportion 240 g / 50 mL is equal to the saturated ratio 480 g / 100 mL
Then, 240 g of sugar in 50 mL of boiling water will make a saturated solution.
Answer: saturated
Answer: A elements that are chemically combined
It´s the right answer i learn it already
