Answer:
The answer to your question is:
Explanation:
Data
Atomic number = Z = 28
Mass number = A = 152
Atomic number number = # of protons
Mass number = # of protons + # of neutrons
Then
Protons = 28
Electrons = 28
Neutrons = 152 - 28 = 124

A molecule with the formula ax4e uses sp3d to form its bonds.</span>
Answer:
B) an anion
Explanation:
During bonding atoms may share electron or give out electron . In the case of electrovalent or ionic bonding, electron(s) is/are transferred from one atom to another . The atom that donate the electron are known as donor atom and the atom that receives the electron are known as receivers.
The atom that donate the electron becomes a cation(positively charged) as it lose it electron(s) while the receiver gains electron to become an anion which is a negatively charge ion.
An example of such interaction is between a sodium atom and a chlorine atom. The Na atom lose it electron to become positively charged(cation) while the chlorine atom gains electron to become negatively charged(anion). Both atom bond together losing and gaining electron to fulfill the octet rule.
Na+ + Cl- → NaCl
