What type of reaction is illustrated?

Answer:

-3

Explanation:

Given parameters:

Number of protons = 7

Number of neutrons = 8

Number of electrons  = 1 0

Unknown:

Overall charge on the nitride ion = ?

Solution:

The overall charge on an specie can be determined by;

  Charge = number of protons - number of electrons

  Charge  = 7 - 10

  Charge  = -3

A nitride ion has 7 protons, 8 neutrons, and 10 electrons. –3 is the overall charge on this ion. Therefore, the correct option is option A.

Ionic force An ion's electrical charge is produced when a number of electrons from a single atom or set of atoms are gained (creating a negative charge) or lost (creating a positive charge). Mineral bonding strength is significantly influenced by ionic charge (for instance, Fe3+ forms a stronger link than Fe2+ with identical ions).

Which elements inside a crystal lattice can be substituted for one another. Electrostatically applied opposite charges provide the ionic connection between ions. MgO is the final form of magnesium oxide. A nitride ion has 7 protons, 8 neutrons, and 10 electrons. –3 is the overall charge on this ion.

Charge = number of protons - number of electrons

Charge  = 7 - 10

Charge  = -3

Therefore, the correct option is option A.

chemical

Explanation:

Salt changes the chemical makeup of the water and allows it to get colder than what it would normally freeze at.

Answer:

4 energy levels/rings

Explanation:

By the atomic model proposed by Niels Bohr, the electrons orbit around the nucleus in shells having different energy level each with the ability to contain a given maximum amount of electrons.

The closest shell to the nucleus named the K shell, can have a maximum of two electrons, the next shell known as the L shell can have 8 electrons while the next shell, M, can have a maximum of 18 electrons

The arrangement of the periodic table is based on the number and location of electrons such that elements in the 4th row (period 4 elements) have three completed energy levels/rings before, their valence ring making the total number of rings = 4 energy levels/rings.

Answer:

In Niels Bohr's theory of the atom, electrons absorb and emit radiation of fixed wavelengths when jumping between fixed orbits around a nucleus. The theory provided a good description of the spectrum created by the hydrogen atom, but needed to be developed to suit more complicated atoms and molecules.

Explanation:

Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun
