Which statements about a phosphorus atom, P, are correct?
Elenna [48]

Answer:

3. The proton number is 15.

Explanation:

Phosphorus, P is the element with the atomic number = 15. The atomic number = Number of protons. That means:

3. The proton number is 15.

Now, the number of protons = Number of electrons = 15.

And, nucleon number = Number of protons + number of neutrons. The must abundant phosphorus atom contains 16 neutrons and nucleon number is: 15+16 = 31.

Thus, we can know which statement is true.

Which value would be required to estimate the lattice energy for the hypothetical ionic compound MgH2?
Sonja [21]
D, the energy of formation is equal to the dissociation. so from magnesium ions and Hydrogen ions, when they form the lattice energy is equal to formation-dissociation, as they aren't going to dissociate (fixed in lattice) the formation should be the same as the the overall lattice energy.
