Concept explainers
(a)
Interpretation:
The number of covalent bonds formed by each atom is the given molecule and the structure of the given molecule using electron-dot symbols with lines showing as covalent bonds.
Concept introduction:
Covalent bonds are formed by sharing of electrons between atoms.
The valence electrons of Phosphorus are 5 electrons.
The valence electrons of Hydrogen are 1 electron.
(b)
Interpretation:

What is so unusual about water thathydrogen bonding becomes possible?arrow_forwardWhat are the four types of bonds that are found in nature? Include the name of each and define each as you compare them.arrow_forward
- what is a weak bond between hydrogen atom with a partial positive charge(usually O or N) and electronegative atom with a partial negative charge?arrow_forwardHow many total atoms would be in one formula unit of (NH4)3PO4? 20, 4, 18, 16arrow_forwardFigure 2.7 An atom may give, take, or share electrons with another atom to achieve a full valence shell, the most stable electron configuration. Looking at this figure, how many electrons do elements in group 1 need to lose in order to achieve a stable electron configuration? How many electrons do elements in groups 14 and 17 need to gain to achieve a stable configuration?arrow_forward
