two <em>p</em><em> orbitals is true answer boi </em>
Answer: In ionic bonding (a noble gas configuration is formed for each element or ion).
Explanation:
IONIC bonding, which is also called electrovalent bonding involves the complete transfer of electrons from one atom to another in order to attain a noble gas electron configuration.
The noble gases or group 0 elements have a completely filled outermost shell of eight electrons. This makes them generally very stable, that is, unreactive. There is a natural drive for other atoms to attain the electron configuration of group 0 (inert gases) elements. This usually results in atoms entering into chemical combinations by losing, gaining or sharing electrons.
Ionia compound such as sodium chloride
--> have high melting points because alot of heat energy is required to break the attractive forces between the ions;
--> are hard and brittle;
--> are soluble in water;
--> conduct electricity when in solution or molten form because the ions are able to move about, that is, they are electrolytes
Answer:
September 9 at 9pm, the following year
Explanation:
We are given from the question above that;
=> Theo observers a star at 9:00 P.M. on September 9.
Theo will be able to see the exact star at the same position and at the exact time of night again the following year. This is because the stars move at least one degree everyday. Thus, the star will move 360 degree in a year. So, Theo will be able to see the same star by September 9 at 9pm, the following year.
The force by which bodies repel one another.
