What is an atom's electron configuration?
The arrangement of electrons in an atom.
Each shell represents a distinct state of electron?
Each shell represents a distinct state of electron energy.
How many valence electrons dows each carbon atom have?
four. each electron can join with an electron from another atom to form a strong cavalent bond
In a water molecule each hygrogen atom shareswhat with the oxygen atom?
Each hydrogen shares one electron with the oxygen atom.
The electron pair geometry of each carbon atom in an alkane is what?
tetrahedral
What is an atom's electron configuration?
The arrangement of electrons in an atom.
How does the arrangement of electrons change when sodium reacts with chlorine to form sodium chloride?
each sodium atom loses an electron and each chlorine atom gains an electron OIL RIG (Oxidation Is Lost-Reduction Is Gain)
In hydrochloric acid HCl the hydrogen atom orients itself as far away as possible from each other because this arrangement .?
minimizes the repulsion of electron groups
In hydrochloric acid HCl the hydrogen atom orients itself as far away as possible from each other because this arrangement?
APEX minimizes the repulsion of electron groups
Each shell represents a distinct state of electron?
Each shell represents a distinct state of electron energy.
How many valence electrons dows each carbon atom have?
four. each electron can join with an electron from another atom to form a strong cavalent bond
In a water molecule each hygrogen atom shareswhat with the oxygen atom?
Each hydrogen shares one electron with the oxygen atom.
How many different ways can you arrange 4 squares if they have to be joined along an edge and not just at the corners?
If each square is distinct and each edge is distinct and the arrangement is done on a flat surface then there are 23,040 distinct arrangement's. This may seem surprising (surprised me) but if you do all the possible combinations this is the amount that you will get
Why cant a third H atom join an H2 molecule to make a H3?
Each hydrogen atom has one electron to share in a covalent bond,H-Hno more electrons to share if a third hydrogen tried to enter this bonding arrangement.
How many electron orbitals does this atom chlorine have?
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5. Each separated letter in that notation represents a distinct electron orbital. Therefore, there are 5 electron orbitals in chlorine.
How many electron pairs are on the boron atom in BCl3?
There are exactly three electron pairs attached to the Boron atom, each one of them bonded to a chlorine atom as well.
What holds atom in covalent compound?
Each atom in a covalent bond shares at least one electron with another electron of another atom to maintain the covalent bond.
