3.01 quiz: atomic number and the periodic law ps which of the following characteristics was not included in dmitri mendeleev's periodic table? distribution of elements determined by electron configuration what is the primary atomic characteristic that mendeleev used to organize the periodic table? atomic mass mendeleev left several blank spaces in his original periodic table. what did those spaces represent? elements that had yet to be discovered according to the periodic law, what is the relationship between elements and periods? element properties repeat from period to period. which of these sets of elements has similar properties? consult the periodic table. strontium, magnesium, calcium, beryllium

The answer is Dissemination of components controlled by electron design.  

Explanation:

the Aufbau rule, the Pauli rejection guideline, and Hund's rule,tell you how to discover the electron designs of particles. As indicated by the aufbau standard, electrons possess the orbitals of most reduced vitality first, Pauli-prohibition rule, and Hund's Rule. The electronic setup of cations is doled out by evacuating electrons first in the peripheral p orbital, trailed by the s orbital lastly the d orbitals.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
