Interpretation:
The number of electrons present in Se2 - ion should be determined.
Concept Introduction:
All neutral atoms have same number of electrons as that of protons known as the
The loss or gain of electron results in the formation of ions. The loss of electron forms cation results in positive charge on parent atom whereas the gain of electron forms anion results in negative charge on parent atom.
Interpretation:
The number of electrons present in Br- ion should be determined.
Concept Introduction:
All neutral atoms have same number of electrons as that of protons known as the atomic number of the element. Every element has a unique atomic number through which it is identified. The number of protons remain intact.
The loss or gain of electron results in the formation of ions. The loss of electron forms cation results in positive charge on parent atom whereas the gain of electron forms anion results in negative charge on parent atom.
Interpretation:
The number of electrons present in Cr3 + ion should be determined.

- The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes.
