B. the frogs are a limiting factor for the gnats
the frogs limit the reproduction of the gnats, and therefore with less frogs the gnat population can increase
Simply look at the periodic table and fill in what you know based on the table
The number of protons = atomic number
The number of electrons, Which is the same as the atomic number for atoms.
The number of valence electrons that is given by the group that the element is in, the top number of each column in the periodic table.
Reduction refers to a chemical reaction in which electrons are gained by one of the atoms involved in the reaction and at the same time lowering of an oxidation state of that atom takes place.
In the given case, the reduction occurs at the cathode. In aqueous, V (vanadium) is present in +5 oxidation state that on reduction modifies to vanadium (aq) with +1 oxidation state.
The half reaction is:
V⁵⁺ (aq) + 4e⁻ → V¹⁺ (aq)
Answer:
Explanation:
the number above the letter is the atomic number and the other on the bottom is the atomic mass . and the mass number is the atomic mass . and protons is the number above the letter along with neutrons electrons you just do atomic mass - atomic number = electrons
example 1 -2= 1 so there is the atomic number of 1 and atomic mass of 2
