Answer:
The cause of periodicity in properties is the repetition of similar outer electronic configuration after certain regular intervals. For example, all the elements of group 1 i.e. alkali metals have a similar outer electronic configuration, ns1.
What is the actual yield of a reaction?
A. The calculated amount of product
B. The fractional amount of product
C. The predicted amount of product
D. The measured amount of product
D
Answer:
A <u>tetraquark</u> in physics is an <u><em>exotic meson composed of four valence quarks</em></u>.
Explanation:
It has been suspected to be allowed by <u><em>quantum chromodynamics</em></u>, the modern story of strong interactions.
Hope it helps.
The answer would be 2. <span>an ion polarizes a nearby neutral atom, so that the part of the atom nearer to the ion acquires a charge opposite to the charge of the ion, and the part of the atom farther from the ion acquires a charge of the same sign as the ion
In neutral atoms, the negative and positive charge spread evenly. The charge from an ion could create an electric field that will attract the charge of the neutral atoms.
The neutral atoms charge sum still zero, but the distribution of charge could be changed.</span>
