The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
its Atomic Mass.
When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high-energy electrons make photosynthesis work
it is something to do with electrons and being charged!
Answer: Level C
The trophic level that contains the organisms that are the source of all chemical energy used in an ecosystem is called the producer level. This level contains the organisms that can make their own food.
Outermost energy level is full if there are 8 electrons in the valence shell.
helium
valence electrons are the electrons in the outermost energy level
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Halogens have six valence electrons in the outermost energy level.
Noble gases (except for helium which has 2 valence electrons).
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
The element is phosphorus and it contains 5 valence electrons.
The electrons on the outermost energy level of the atom are called valence electrons.
