Answer:
Wt Avg At Mass = 39.0229 amu
Explanation:
The Weight Average Atomic Mass in atomic mass units (amu) is the sum of the Weight Average Mass contributions of each isotopic mass. That is,
Wt. Avg. At. Mass (amu) = ∑ Wt. Avg. Contributions of each isotopic mass
Wt. Avg. Contribution = fractional abundance x isotopic mass(amu)
For this problem data:
Isotope %Abundance fractional Isotopic Wt Avg Isotopic
abundance mass(amu) Contribution (amu)
1 9.67% 0.0967 38 3.6746 amu
2 78.68% 0.7868 39 30.6852 amu
3 11.34% 0.1134 40 4.5360 amu
4 0.31% 0.0031 41 0.1271 amu

Wt. Avg. Atomic Mass (amu) = ∑ Wt. Avg. Contributions = 39.0229 amu
Answer:
D. Conductor
Explanation:
Conductors are the substances which are good conductors of both heat and electricity. These substances have free electrons present around the nucleus which is the main reason for conduction. Metals like copper, gold, silver, iron and steel etc are the examples of conductor. Gold is best conductor but cannot be used due to high cost. After gold, copper is the best conductor so that's why it is used extensively in electric wires.

<span>The ground state of the atom is its lower energy state. The correct electron configuration for a ground-state atom with 7 electrons is 1s^2 2s^2 2p^3. The powers that are exponents represent the number of electrons in the configuration and the 1s, 2s and the 2p represent the orbital.</span>
