Water is a simple triatomic molecule. Each O-H covalent bond in the water molecule is polar. Because of its greater electronegativity, the oxygen atom attracts the electron pair of the covalent O-H bond and acquires a partial negative charge. The hydrogen atoms, being less electronegative than the oxygen, acquire a partial positive charge. The atoms of the water molecule are joined at a 105 angle. As a result, the partial charges on the individual atoms do not cancel one another and the molecule is polar. Because water molecules are polar, they attract one another. The hydrogen of one molecule is attracted to the oxygen of another molecule. This attraction is termed hydrogen bonding and it is stronger than other polar attractions.
A molecule, if the species is molecular. If the species is ionic, it is the unit cell, since it cannot be broken down into individual molecules.
No, "agreeable" is not a compound word. It is a standalone word that is used to describe something that is pleasing or pleasant.
Yes, the term 'math class' is a open spaced compound noun, made up of the noun 'math' to describe the noun 'class'. When a noun is used as an adjective to describe another noun, it's called an attributive noun. Examples like computer screen or road sign become accepted as compound nouns when they are commonly used for that thing.
It lacks straight line segments (sides) - it's a set of compound curves. Although - you *could* describe it as a *very large* set of *very short* straight lines.
Compound adjectives are only compound before the noun.
Really i need some help on this one!? Thanks
The chemical composition and structure are important.
true yes it can
This is possible because for a specific empirical or structural formula correspond inherent specific properties, dependent on the composition and structure.
to be a hard substance.
a compound has physical properties that
the properties of a compound are not the same as the elements that form them.
The individual elements from which the compound is formed
what controls the properties of a compound
I'm pretty sure it's false... if you change a group the compound has to change because its not the same anymore
Compounds have different properties from the elements that make them. ... The properties of a compound depend not only on which atoms the compound contains, but also on how the atoms are arranged.
No: Both characteristics are important, and they are, of course, interrelated.
