A water molecule consists
of one oxygen atom bonded to two hydrogen atoms by covalent bonds
. Since oxygen is more electronegative as compared to hydrogen atoms, the shared electrons are attracted towards the oxygen atom.
What best describes a water molecule?
A water molecule consists
of one oxygen atom bonded to two hydrogen atoms by covalent bonds
. Since oxygen is more electronegative as compared to hydrogen atoms, the shared electrons are attracted towards the oxygen atom.
Which of the following represents a water molecule?
A water molecule consists of three atoms;
an oxygen atom and two hydrogen atoms
, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre.
What describes the H2O molecule?
Water
(chemical formula: H2O) is a transparent fluid which forms the world’s streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds.
What is in a water molecule?
A water molecule consists of
two atoms of hydrogen linked by covalent bonds to the same atom of oxygen
. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
Is water an element or compound?
water, a substance composed of the
chemical elements hydrogen and oxygen
and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds.
What are the two components of water?
To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements:
hydrogen and oxygen or
, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature.
Is water an atom or molecule?
Water is
a simple molecule
consisting of one oxygen atom bonded to two different hydrogen atoms. Because of the higher electronegativity of the oxygen atom, the bonds are polar covalent (polar bonds).
How many elements are in water molecules?
A water molecule has
three atoms
: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H
2
O.
Can we see water molecules?
Water consists of tiny particles called molecules.
You can’t see them
, not even under a microscope, they are much smaller than that. But even each water molecule consists again of smaller particles called atoms.
What is the chemical name for the formula CO2?
Carbon dioxide
(chemical formula CO2) is an acidic colorless gas with a density about 53% higher than that of dry air.
Why is it called H2O?
The scientific name for water is H2O. It is called H2O
because it has two atoms of hydrogen (H) and one atom of oxygen (O)
. … Water molecules move so fast that they actually break apart from each other and escape into the air as water vapor or steam.
Why is water called water?
The word water
comes from Old English wæter
, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (“water”; “wet”).
How water molecule is formed?
When two hydrogens and an oxygen share electrons via covalent bonds
, a water molecule is formed. An example of a simple chemical reaction is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H
2
O
2
).
