The electrons of an atom located the furthest distance from its nucleus in the highest energy occupied atomic orbitals, are known as the valence electrons of an atom. From the row (period) and group (column) position of a chemical element in the periodic table, ...
Carbon monoxide contains covalent bonds as their atoms share the electrons so that their valence shell is filled but weak intermolecular forces join their molecules together which can be easily broken and thus they have a low melting point.Carbon dioxide also has a low ...
The valence shell of the element X contains 2 electrons in a 5s subshell. Below that shell, element X has a partially filled 4d subshell. What type of element is X? (a) Main group element (b) Chalcogen (c) Halogen (d) Transition metal (e) A...
What family on the periodic table of elements has a full outer electron shell? Which is the most reactive element in the period table? Which of the elements in the following periodic table are lanthanides? In period 2 of the periodic table, which group conta...
to the periodic table to explain which metals best conduct electricity. The number of valence electrons in an atom is what makes a material able to conduct electricity. The outer shell of the atom is the valence. In most cases, conductors have one or two (sometimes three) valence electrons....
- In a neutral atom, if it loses 2 electrons, it must have had 2 electrons in its valence shell. - Conclusion: This match is correct. 3. Analyzing Option (B): - Unipositive ion: This means the ion has a charge of +1, indicating it has lost 1 electron. - If it has 7 elect...
Step 1: Identify the ElementsThe elements provided are:- A: Argon (Ar)- B: Hydrogen (H)- C: Iron (Fe)- D: Neon (Ne) Step 2: Analyze Noble GasesArgon and Neon are noble gases. Noble gases are characterized by having a complete valence shell, which makes them generally unreactive. ...
Unpaired Electrons:Unpaired electrons can be considered as those electrons that alone can occupy the atomic orbitals. An atomic orbital has the capacity to contain two electrons but if it contains only one electron then that electron is called an unpaired electron....
Which group of the periodic table is known as the halogens? List them. What group in the periodic table has the valence-shell configuration ns2np4? What is the most reactive metal in the periodic table? Which of the following groups contains react...
