A nitride ion has 7 protons, 8 neutrons, and 10 electrons. What is the overall charge on this ion?
–3
–2
0
+3
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.
What is ionic charge?
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.

explain the coin and feather experiment. what conclusion can be drawn from experiment
In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach the ground at the same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

How many joules are released when 30.0 g of H2O(g) condenses at 100°C and cools to 10°C
Heat released : 79086 J
Further explanationCondenses :
1. phase change (gas - liquid) : heat of vaporization (ΔH vap for water = 2260 J/g)
2. cools from 100 - 10 : (Q=m.cΔT)
1. Q=m.ΔH vap
[tex]\tt Q=30\times 2260=67800~J[/tex]
2. Q=mc.ΔT(c water = 4.18 J/g C)
[tex]\tt Q=30\times 4.18\times (100-10)\\\\Q=11286~J[/tex]
Q tot = 67800 + 11286 = 79086 J
schroedinger thought that electrons
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:
If an element is on the 4th row of the periodic table...how many energy levels/rings would you need to draw a Bohr 's model of the element's atom?
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.

6. Classify each compound as ionic or molecular based on its properties.
Substance Melting Point Solubility Conductivity Classification
1 -55 oC poor poor
2 396 oC good good
3 0 oC not tested poor
4 200 oC good good
5 20 oC good poor
Answer:
1. c
2. ionic
3. c
4. ionic
5. alloy or ionic
Explanation:
The compound classification.
The compounds are classified as per several different criteria and one common elements is the specific element that is present this makes it an iconic or a molecular. The presence of the oxides, hydrides, and various atomic groups.
Hence the answer is melting point to conductivity classified as c, iconic, c, iconic, and alloy.
A poor conductor of electricity will have a conductivity classification of c. The 396 good conductors will be iconic and a 0 C not teste will have a conductivity of c. The 200 C of good conductor will be iconic and 20 C of good conductor will be alloy or iconic.Learn more about each compound as.

Write a balanced equation for the following reaction;
potassium metal reacts with nitrogen gas to form potassium nitride
Answer:
6K + N₂ —> 2K₃N
Explanation:
K + N₂ —> K₃N
The above equation can be balanced as illustrated below:
K + N₂ —> K₃N
There are 2 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 2 in front of K₃N as shown below:
K + N₂ —> 2K₃N
There are 6 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 6 in front of K as shown below:
6K + N₂ —> 2K₃N
Now the equation is balanced.
When Earth is tilted on its axis why does it orbit the sun ?
Answer:
Here
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
