How many electrons at the maximum can be present in the first shell?
Two electrons can fit in the first shell
How many electrons are in level two of helium?
There are no electrons present in a helium atom in its second energy level.
WHAT Are the two types of electric charges found on electrons and protons?
Protons are positive, and electrons are negative.
When two pairs of shared electrons are present a bond is formed?
Yes. Two pairs of shared electrons would form a double covalent bond.
What is the difference between the energy gap of a semiconductor and a superconductor?
Energy gap in a superconductor is not a constant but depends on temperature. Energy gap in a semiconductor is a fixed quantity which does not depend on temperature. The excited quasiparticles or cooper pairs are produced two at a time hence the gap is 2Delta0. In a semiconductor the gap is the energy needed to excite 1 electron into the conduction band. The ground state in a superconductor is made of superconducting cooper pairs , above the gap the electrons are unpaired , the cooper pairs have lower energy. Conduction takes place in the lower ground state in Superconductors , where in semiconductors the electrons conduct from the conduction band. In a superconductor the gap is tied to the fermi level , while in a semiconductor it is fixed to the lattice in reciprocal space.
What are two types of participles?
Present and past are the only types of participles in English.
What are the two types of participle?
The two types of participles are present participles and past participles. Present participles typically end in "-ing" and are used to form continuous verb tenses, while past participles often end in "-ed," "-d," "-t," "-en," or "-n" and are used to form perfect verb tenses.
What are bonds in atoms?
Two types: Covalent, in which they share valence electrons to form molecules. Ionic, in which they give or lose valence electrons two each other.
What are the two types of motion that the electrons of an atom exhibit?
Electron spin and Electron revolution
How many bonding pairs of electrons are there in water?
There are four electrons, which is two pair.
When two different types of atoms share electrons to complete an octet what type of bond is formed?
covalent - which means "sharing of valence electrons"
Do two carbon atoms form a nonpolar covalent bond?
Yes, the two are the same element and equal sharing of electrons are present
