He proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another.
Answer:
Explanation:
The objective here is to draw the Lewis structure for the polyatomic trisulfide anion and to be sure all resonance structures that satisfy the octet rule are included.
The Lewis structure for Polyatomic trisulfide anion
The first step is to the layout the skeleton of the Polyatomic trisulfide anion
S S S
However, the next step is to make sure we fill in the bonding pairs of electrons on the central atom.
Then , we move over to filling the lone pairs electrons before we finally have the Lewis structure for Polyatomic trisulfide anion as shown in the image below.
Answer:
yes
Explanation:
a solid melting into a liquid is a kind of a physical change and it definitely alters the appearance of the substance. A liquid evaporating into gas is also an example of a physical change.
An ion is an atom with a different number of electrons than its number of proton, the charge of an ion is not net
need more information to find the charge but it can't be 0 if it is an ion
an ionic bond is when 2 or more ions attract negative and positive
