The electron dot diagram tells
us about how many electrons are being shared between atoms. Also, the number of
valence electron to be shared corresponds to the group number the element
belongs. Say for example H2O, hydrogen has one valence electron and oxygen has
two valence electrons.
1. An ionic bond is an attraction between oppositely charged ions. A covalent bond is sharing of electrons between atoms.
2. A bond between two atoms
3. covalent bond
4. They have different properties because the arrangement of atoms is different.
5. Mutual attraction between the nuclei and electrons in two different atoms
You are made of mostly 6 elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus. Some of these elements combine to form compounds in your body.
Answer:
J 9. , indicates the most sudden change in temperature
Answer:
Explanation:
The<em> energy of a photon</em>, E, can be calculated with the Planck-Einstein equation:
Where:
- h is Planck's constant 6.626×10⁻³⁴ J.s, and
- f is the frequency of the photon or electromagnetic radiation.
Substituting with your data:
Now multiply by Avogadro's number to obtain the energy of one mole of photons:
