(a)
Interpretation:
The maximum number of electrons which can hold by shell No. 1 should be determined.
Concept Introduction:
In a planetary model of an atom, negative charged electrons are arranged around the positive charged electron in a series of shells which is like orbits.
The electrons present in the outermost energy level or shell is known as valence electrons. These electrons are available for bonding and outermost shell is known as valence shell.
(b)
Interpretation:
The maximum number of electrons which can hold by shell No. 2 should be determined.

(c)
Interpretation:
The way should be described by which answers to a) and b) are contained in periodic table.
Concept Introduction:
The distribution of electrons in atom into orbitals is said to be electronic configuration. The electronic configuration for every element present in the periodic table is unique or different.
Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods. The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents
In periodic table, different blocks within the periodic table correspond to the s, p, d and f sublevels. Thus, on the basis of increasing atomic number in the periodic table, electronic configuration of atoms can be written.

Organic Chemistry: A Guided Inquiry
- Use the data in Table 3.1 to plot the logarithm of ionization energy versus the number of electrons removed for Ne. Describe the electronic structure of the Ne atom.arrow_forwardTrue or false? In general, a large atom has a smaller electro-negativity. Explain.arrow_forwardA student draws the picture of ammonia (NH3) in the box below, left, and predicts it will be a flatmolecule with HNH bond angles of exactly 120°. Unfortunately, the student left something out. a. What did the student omit from his drawing? b. What is the actual HNH bond angle of ammonia (based on the draw g above, right)? c. Explain why water, ammonia, and methane (shown below) all have about the same bondangles (close to 109.5°) even though they have different numbers of bonds.arrow_forward
- 1a) Create a drawing of the lewis structure of the ion ?3 2+, show your work (show all your work, total electron count, etc). b) How many total nodes are present in a 4d orbital? How many are radial and how many are angular?arrow_forward1. Can you help me what does mean for the Valence Shell Electron Pair Repulsion (VSEPR) Theory and examples too? 2. Can you help me with the explanation of the diatomic molecule, small molecule, large molecule and examples too?arrow_forwardYou hear a student from a nearby group say that “Electron domains repel one another.” Citeevidence from Figure 1.2 to support or refute this statement.arrow_forward
