Chemistry
1 answer:
olga nikolaevna [1]2 years ago
4 0

Answer:

            Option-A is the correct answer

Explanation:

Lithium belong to group 1 metals. Hence, it can loose one electron to form lithium ion i.e. Li⁺¹ or Li⁺

While, Nitrogen is non-metal and hence has the ability to gain the electron lost by lithium metal. Furthermore, Nitrogen can gain maximum 3 electrons to acheive noble gas configuration. Hence, three Li atoms will loose their electrons and Nitrogen will gain those three electrons to form nitride ion i.e. N³⁻.

How to draw an.electron dot diagram. 1 write the chemical aymbo of the atom.2. Determine the number of valence electron the atom
almond37 [142]
Basically, an electron dot diagram is just a diagram showing the number of valence electrons a certain atom has (valence electrons are electrons in the outer-most electron level of an atom). The 5 steps they give you just tell you the order of where to put each dot.  The picture I attached gives a better representation.

The number around the symbol shows the order of where you would put the dot.  The 1 and the 2 on the top show that the first two dots go there, and the 3, 4, and 5 go around the rest of the sides.  When it gets to 6, 7, and 8, the numbers go back around to fill  in each side twice.

stiv31 [10]

Answer:

See explanation

Explanation:

Given Einstein's theory of relativity, we have that;

E= mc^2

m= mass of the substance

c= speed of light

For one gram of the substance,

E= 1 ×10^-3 × (3 × 10^8)^2

E = 9 × 10^13 J

For 8.7 g of matter;

E = 8.7 × 10^-3× (3 × 10^8)

E= 7.83 ×10^ 14 J
