Answer:
Si₁₄ = 1s² 2s² 2p⁶ 3s² 3p²
Explanation:
Silicon is present in group 14 of periodic table.
It is blue-gray color metalloid.
Its atomic mass is 28 g/mol.
It is mostly used to make allow.
The most important alloy are Al-Si and Fe-Si. These are used to make different machine tools, transformer plates, engine etc.
Its atomic number is 14 and electronic configuration can be written as,
Electronic configuration:
Si₁₄ = 1s² 2s² 2p⁶ 3s² 3p²
The noble gas electronic configuration or abbreviated electronic configuration can also be written.
Si₁₄ = [Ne] 3s² 3p²
The atomic number of neon is 10. Its electronic configuration is,
Ne₁₀ = 1s² 2s² 2p⁶
That's why we write [Ne] for 1s² 2s² 2p⁶ in abbreviated electronic configuration of Si.
Answer:
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Answer:
Bar graphs have an x-axis and a y-axis like most bar graphs, like the one above, the x-axis runs horizontally (flat).
Sometimes bar graphs are made so that the bars are sidewise like in the graph below. Then the x-axis has numbers representing different time periods or names of things being compared.

Answer:
0.2M
Explanation:
Data obtained from the question include:
C1 = 2.0 M
V1 = 100mL
V2 = 1000mL
C2 =?
Using the dilution formula C1V1 = C2V2, the molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
2 x 100 = C2 x 1000
Divide both side by the 1000
C2 = (2 x 100) / 1000
C2 = 0.2M
The molarity of the diluted solution is 0.2M
