What occurs when there is an unequal sharing of electrons between atoms?
Part of the Molecule will be slightly negative and the other slightly positive. One example is water. The oxygen atom hogs the electrons leaving the oxygen slightly negative and the hydrogen slightly positive. This makes the water molecules slightly "sticky" and the water molecules clump together. If this didn't happen then water would boil at -120 deg C intead of +100 degrees.
What characteristics of the water molecule allows it to play an extensive role in many biological reactions?
The polarity of the water molecule, due to its uneven distribution of electrons, allows it to form hydrogen bonds with other molecules. This makes water an excellent solvent, enabling it to dissolve a wide range of molecules involved in biological reactions. Additionally, water's high specific heat capacity and ability to moderate temperature changes help maintain stable conditions for biological processes.
Why dipole moment does NF3 have?
NF₃ has a dipole moment because the nitrogen atom is more electronegative than the fluorine atoms, leading to an unequal sharing of electrons in the molecule. This results in a net dipole moment, with the nitrogen pulling electron density towards itself, creating a partial negative charge, and the fluorine atoms having a partial positive charge.
Is oxygen atom has an overall negative charge with the hydrogen atoms having an overall positive charge?
All atoms have the same overall charge with the exception of ionization (electrons are lost or gained). since there are the same amount of protons and electrons in an atom, the negative and positive cancel each other out.
What does having an unequal number or protons and electrons do to an atom?
An unequal number of protons and electrons creates an ion, which results in a net electric charge. If an atom gains electrons, it becomes negatively charged (anion), while losing electrons leads to a positive charge (cation). This charge imbalance affects the atom's chemical behavior and its interactions with other atoms.
What types of bonding involves the unequal sharing of electrons?
Polar covalent bond
What is polar covalent molecule?
A polar covalent molecule is a molecule with a covalent bond where the electrons are shared unequally between the atoms, leading to one atom having a partial positive charge and the other having a partial negative charge. This unequal sharing of electrons creates a separation of charge within the molecule, making it polar. Examples include water (H2O) and ammonia (NH3).
Two hydrogen atoms form a hydrogen molecule by?
Two atoms can interact to form molecules by sharing a pair of electrons. This process is known as covalent bonding.
Is phosgene polar?
It is polar, albeit only slightly due to oxygen having a larger electronegativity than chlorine.

How many electrons are shared in a water molecules?
In a water molecule, two electrons are shared between the oxygen atom and each of the two hydrogen atoms, forming two covalent bonds. This sharing of electrons creates a stable structure for the water molecule.

How does water form a covalent bond?
it can by having an equal sharing of electrons
An atom that has a positive or negative charge due to having unequal numbers of protons and electrons?
An atom that has a positive or negative charge due to having unequal numbers of protons and electrons is called an ion. If an atom gains electrons, it becomes a negatively charged ion (anion), and if it loses electrons, it becomes a positively charged ion (cation).
What is the Covalent Bond for Chlorine and Chlorine?
a covalent bond means sharing of electrons the outer most electrons on chlorine shell is 7since chlorine is a diatomic molecule (cl2) it comprises of 2 chlorine atoms having 7in each valence shell. for this molecule to be stable it must attain the stable octet configuration 8electrons in their outer shell x x x Cl x x x x 1 o o o o Cl o o o so they share the electrons (marked with a hyphen) to attain the stable configuration. this sharing of electrons between two chlorine molecules is called sharing of electrons within chlorine
Is oxygen atom has an overall negative charge with the hydrogen atoms having an overall positive charge?
All atoms have the same overall charge with the exception of ionization (electrons are lost or gained). since there are the same amount of protons and electrons in an atom, the negative and positive cancel each other out.
