Answer:
D
Explanation:
The atom splits into two nuclei
Answer:
a. True
Explanation:
The bonds between atoms are called chemical bonds. These bonds act as though they were a spring holding these atoms together.
When the atoms in a given bond are compressed by decreasing their distance of separation from their equilibrium position, a force provided by the bond tries to prevent these atoms from getting too close than usual. If on the other hand the atoms are stretched by increasing their distance of separation from their equilibrium position, a force provided by the bond tries to pull these atoms together again. This behaviour of the bond is what makes it to be considered as being similar to a spring.
3. Ampere is the base unit for electric current.
Answer: Lanthanide or Lanthanides
Explanation: Sorry that I don’t have an explanation. I just answered the question correctly myself. <33
Answer:
Two electrons each!
Explanation:
The question pretty much requires us to find the oxidation number of Zinc in the compound.
Zn3P2
Following oxidation number rules;
O.N of Zn3P2 = 0
.Since phosphorus has valence of 5, it needs three more electrons to achieve its octet state. Hence;
Oxidation number of P = -3
Let oxidation number of Zn = x
We have;
3x + 2 (-3) = 0
3x + (-6) = 0
3x = 6
x = 6/3 = 2
This means each zn electrons lost 2 electrons.
