Answer 1: Atoms gain valence electrons to form anions.
Explanation:
Anions are negatively charged species of an ions. Anions are formed when atoms with nearly complete octet gains electrons.
Answer 2: Emission spectrum
Explanation:
When ever electron jumps from higher energy to lower energy level energy is emitted out in the form of light.The wavelength of the light is given as :
, E = energy, c= speed the light, h= planck constant
Answer 3: Two atoms of silicons could combine by fusion in order to create nickel.
Explanation:
Silicon has atomic number of 14 with atomic mass of 28 u.
nickel has atomic number of 28 with atomic mass of 59 u.
Two different isotopes of silicon atom will fuse together to give nickel.
Answer:
Explanation:
Hello there!
In this case, according to this equilibrium temperature problem, we can set up the following equation to relate the mass, specific heat and temperature change:
Thus, we solve for the mass of cobalt as shown below:
