b. They have similar physical qualities.
c. They have identical numbers of electrons in the outermost level.
d. They were discovered in the same location.
Answer: Based on experimental data
Explanation: The hypothesis is not the ultimate proven theory, the more a preliminary assumption on the basis of which further research is carried out with the help of experiments in order to prove the hypothesis as accurate. If the experiments carried out showed that the hypothesis is wrong, it is necessary to revise the hypothesis and set up a new experiment.
Answer:
a b d
Explanation:
Answer:
B.
Explanation:
The electron dot diagram which is also known as the Lewis electron dot diagram is a diagram that shows an atom's valence electrons by placing dots, which represent the valence electrons of the element, around the elements symbol
The element for which the electron dot diagram is found = Neon, Ne
The atomic number of neon, Ne = 10
The electronic configuration of neon = 1s²2s²2p⁶
The valence shell is the outermost shell having the highest value of the coefficient of the orbitals, n = 2s²2p⁶
The number valence electrons in neon = The number of electrons in the valency shell = 2 electrons + 6 electrons = 8 electrons
The number of valence electrons in neon = 8
Therefore, the electron dot diagram for neon will have 8 dots located around the Ne symbol, which gives option B
