Hello,
A molecule is
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
I hope this helps
Answer: 13.5g
Explanation:
Moles = mass/molar mass
Molar mass of water= 18gmol-1
0.75=m/18
m= 17*0.75= 13.5g
A. The A group number tells which period the valence electrons are
in
B. The A group number tells how much mass the elements have.
C. All elements in the same A group will have the same number of
valence electrons.
D. All elements in the A group will have the same valence electrons
as the B group.
Answer:
All elements in the same A group will have the same number of
valence electrons.
Explanation:
Group A has 1 valence electrons.
Ionic bond is formed when there is a transfer of electron(s) from metallic atom to non-metallic atom.
The correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons
Ionic bond exist between a metal and a nonmetal.
In this bonding, the metal losses it's valence electron to form a stable metallic ion, while the nonmetal receives the electron from the metal to form a stable nonmetallic ion which results in the formation of an ionic compound.
With the above information, we can see that ionic bond involves a transfer of electron(s).
Thus, the correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons.

Answer: B
Explanation:
Ionic bonding is the complete transfer of electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
