How to find it- Add up the mass of protons and neutrons
Answer:
The correct answer is a. chemical bond. See the explanation below, please.
Explanation:
The resulting electrostatic interaction is called ionic bond between ions of opposite charge (one negative and one positive). This allows the attraction between both charges, constituting a chemical compound. Eg the Sodium (Na +) ion combines with the Chlorine (Cl-) ion forming Nacl (sodium chloride, known as table salt).
Ν= c/λ
λ= 486 nm * ( 1 m / 1x10^9 nm) = 4.86 x10^-7 m
v= (3.00 x 10^8 m/s) / (4.86 x10^-7 m)
v= 6.1728395x 10^14 s^-1
= 6.14 x10^-14 Hz
Because the equator is closer to the sun, the sun rays hit the earth’s surface which causes the temperature to be warm at a higher angle at the equator,
Acidic, basic. Also, 7 is neutral. Hope it helps! :)
