A covalent bond is formed when two atoms share one electron each.
In PCl3 there are three bonds to the central atom (P) and one lone pair.. This can be worked out as follows. P has 5 valence electrons, shares three electrons with the chorine atoms (1 each) leaving 2 electrons on the P as a lone pair. In VSEPR theory this is an AX3E compound like ammonia.
No. Electrons are subatomic particles, meaning they are smaller than atoms. Atoms contain electrons, not the oter way around.
more electrons because all atoms want to be like noble gases and will either give or take electrons to obtain 8 electrons so atoms with either 1 or 2 electrons would wither give off 1 or 2 electrons depending on how many then had
Four, because Carbon has 4 outer free electrons so each Hydrogen shares one electron in a covalent bond
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
Hydrogen atoms have one valence electron which is also the only electron they have.
In a water molecule, oxygen shares electrons with hydrogen atoms to form covalent bonds. Oxygen has 6 electrons in its outermost energy level, while hydrogen has 1 electron in its outermost energy level. Oxygen shares one electron with each of the two hydrogen atoms, forming two covalent bonds.
In CH2O, there are a total of 12 valence electrons. Carbon shares 4 electrons, each hydrogen shares 1 electron, and oxygen shares 2 electrons. Therefore, a total of 10 electrons are being shared in CH2O.
An oxygen atom has 6 electrons in its outermost energy level. When it shares electrons with two hydrogen atoms to form a water molecule, oxygen will share 2 of its electrons with each hydrogen atom, allowing each hydrogen to complete its outermost energy level with 2 electrons. This results in oxygen having a full outermost energy level with 8 electrons.
Two oxygen atoms connect via a double covalent bond, sharing a total of four electrons (two from each atom). This bond allows the oxygen atoms to achieve a stable electron configuration by filling their outermost energy level with eight electrons.
Hydrogen shares its electrons to complete the octate so it gains 1 electrons. it can also its electrons.
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
In PCl3 there are three bonds to the central atom (P) and one lone pair.. This can be worked out as follows. P has 5 valence electrons, shares three electrons with the chorine atoms (1 each) leaving 2 electrons on the P as a lone pair. In VSEPR theory this is an AX3E compound like ammonia.

Covalent compounds are a type of compound where two nonmetals combine, by sharing electrons. For nonmetals to become stable they usually require 1,2 or 3 more electrons. Hence when two nonmetals combine, they can share electrons. For example the covalent compound Carbon Dioxide has a formula of CO2 that is 1 carbon and two oxygen atoms. Carbon needs 4 more electrons while oxygen only needs two more. Hence each oxygen forms a double covalent bond with the central carbon. The each oxygen atom shares two of its electrons with carbon and carbon shares two of its electrons with each oxygen
