Answer:
Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it. Covalent bonds form when sharing atoms results in the highest stability. Other types of bonds besides ionic and covalent chemical bonds exist, too.
Answer:
a. 4, b. 6, c. 4, d. 2
Explanation:
The coordination number (CN) of a complex of a compound is the number of bonds that a metallic ion does with the binders, which can be equal or not.
a. The metallic ion is the iron (Fe), and it's bonded to 2 gly and 2 H2O, thus, CN = 4.
b. EDTA is a hexadentate molecule, thus, it forms 6 bonds with the metal Cr, and CN = 6.
c. The metal is Pt, which has 4 bonds with NH3, thus CN = 4.
d. The metal is Ag, which forms 2 bonds with NH3. NO3 is bonded with the structure and not with the metal. Thus, CN = 2.
Hello,
Your question states: If an atom of nitrogen binds with three hydrogen atoms to form a molecule of ammonia, how many lone pairs of electrons does nitrogen have?
Your answer would be:
B. Three
Brainliest!?!
Hope this helps!
Have a great day:)

Activation Energy. All chemical reactions, even exothermic reactions, need a certain amount of energy to get started. This energy is called activation energy. For example, activation energy is needed to start a car.
From the outer or highest energy shell.
The atomic number 13 implies this electronic configuration 1 s2 2s2 2p6 3s2 3p1.
There are three electrons in the outer shell (3s2 3p1)which are those that the atom can loose more easily (precisely for having the higher energy or being farther from the nucleus)
