Answer:
your welcome
Explanation:
The electronic configuration of chlorine can be written as 2, 8, 7. 2, 8, 7 electrons are distributed in the shells K, L, M respectively. Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.
Answer: synthesis
Explanation:the answer given earlier does have a comment on it correcting but I missed that the first time I visited this question.
The principal quantum number, <span>nn</span>, designates the principal electron shell. Because n describes the most probable distance of the electrons from the nucleus, the larger the number n is, the farther the electron is from the nucleus, the larger the size of the orbital, and the larger the atom is. n can be any positive integer starting at 1, as <span><span>n=1</span><span>n=1</span></span> designates the first principal shell (the innermost shell). The first principal shell is also called the ground state, or lowest energy state. This explains why <span>nn</span> can not be 0 or any negative integer, because there exists no atoms with zero or a negative amount of energy levels/principal shells. When an electron is in an excited state or it gains energy, it may jump to the second principle shell, where <span><span>n=2</span><span>n=2</span></span>. This is called absorption because the electron is "absorbing" photons, or energy. Known as emission, electrons can also "emit" energy as they jump to lower principle shells, where n decreases by whole numbers. As the energy of the electron increases, so does the principal quantum number, e.g., n = 3 indicates the third principal shell, n = 4 indicates the fourth principal shell, and so on.
The jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml mass of the water in the graduated cylinder is 128.5 gram.
<h3>What is density?</h3>
Density is a amount of a substance per unit area of the volume of the mass and it is the ratio of mass and the volume unit is centimeter cube.
The density of the substance = mass / volume
substituting the value in the equation,
Density = 132.6 / 48.6 = 2.1 centimeter cube.
mass = density volume
mass = 2.1 61.2
mass = 128.5 gram.
Therefore, mass of the water in the graduated cylinder is 128.5 gram if jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml.
