Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!
Answer:
The additional electron does not affect the atomic number nor the mass number. The atomic mass is the sum of neutrons and protons. Electrons are not accounted in atomic mass as their mass is so small, approximately 1/1,836 of a protons mass. Atomic number is the total number of protons of an atom. Chlorine taking in another electron will not change its atomic number. In an ion, the atomic number and atomic mass do not change from the original.
i think..
potassium hydroxide..
Answer:
1.Hydrogen: 1s1 2 - Helium: 1s2
45 – Rhodium: [Kr], 5s2, 4d7 46 – Palladium: [Kr], 5s2, 4d8
47 – Silver: [Kr], 5s2, 4d9 48 – Cadmium: [Kr], 5s2, 4d10
49 – Indium: [Kr], 5s2, 4d10, 5p1 50 – Tin: [Kr], 5s2, 4d10, 5p2
Thus 43 electrons, so the neutral atom has atomic number 43. Look at a periodic table and you see that this element is technetium.
Element Atomic Number Element Symbol Element Electron Configuration
45 Rh [Kr] 4d8 5s1
46 Pd [Kr] 4d10
47 Ag [Kr] 4d10 5s1
48 Cd [Kr] 4d10 5s2
