In PC 1 3 how many atoms bond to the central atom and how many lone pairs are there in it?
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.
Atoms with 1 or 2 electrons on their valence level tend to gain?
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
Are electrons made up of 1 atom?
No. Electrons are subatomic particles, meaning they are smaller than atoms. Atoms contain electrons, not the oter way around.
How many electrons do halogen atoms get when they react?
1
how many hydrogen atoms can be bonded to one carbon atom?
Four, because Carbon has 4 outer free electrons so each Hydrogen shares one electron in a covalent bond
How many covalent bonds are required to connect to oxygen atoms together?
oxygen contains 6 electrons in its outermost shell contains ,to complete its octet it shares 2 electrons and hence form two covalent bonds(1 sigma and 1 pi bond).
How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of water molecule?
In water molecules there are 2 atoms of hydrogen of and 1 atom of oxygen present. each hydrogen atom shares 1 electron with the oxygen atom. So the total number of electrons shared with oxygen are 2,total no. of electrons shared by hydrogen is 2 and the total no. of electrons shared by each hydrogen atom is 1.
How many atoms does electrons have?
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).

How many electrons do hydrogen gains or lost?
Hydrogen shares its electrons to complete the octate so it gains 1 electrons. it can also its electrons.
Which would contain more electrons a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.

No. Electrons are subatomic particles, meaning they are smaller than atoms. Atoms contain electrons, not the oter way around.
How many electrons do halogen atoms get when they react?
1
What is the number of electrons that an atom in the halogen family usually gains of shares?
1
how many hydrogen atoms can be bonded to one carbon atom?
Four, because Carbon has 4 outer free electrons so each Hydrogen shares one electron in a covalent bond
What is the main factor that determines how atoms combine?
What determines how atoms (and molecules) combine is their electron configuration. In particular, what matters most is what the number (and arrangement) of electrons in what is called the valence shell of the atom. These are the outer-most electrons, and it is these that determine how things react and combine with other atoms and molecules
