Boron is one position to the left of carbon on the periodic table. The atomic nurnber of carbon is 6. Given its position on the periodic table, what is the atomic number of boron?
The 100 or so are characterized by $Z_"atomic number"$...which specifies the number of charged particles present in the element's nucleus. $"Z=1, hydrogen; Z=2, helium"$ $"Z=3, lithium; Z=4, beryllium; Z=5, boron;...

In the ground state, each atom of an element has two valence electrons. This element has a lower first ionization energy than calcium. Where is this element located on the Periodic Table?
It is a period or row that is energy level five or more, below calcium on . Two valence electrons places the element in the alkaline earth family or...

Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's position on the periodic table? Do not conduct calculations.
Something worth knowing about deciding between nonpolar and polar is that only two of the same element can form an ideally nonpolar bond. With this in mind, the $"Br"-"Br"$...

A particular element is located in column IVA of the periodic table. How many dots would be placed around the symbol of this element in its electron dot notation?
Column IVA is group 14 on . The in group 14 all have 4 , so the Lewis symbol for elements in this group have 4 dots around them (each...

How do you read the Electron Configuration Periodic Table? For example, if yu wanted to find Mg what would its configuration be?
Subshell notation of magnesium is 2.8.2. We know that magnesium is in Group 2, Period 3. Hence it has an energy level of 3. By doing this, we can...

A sodium atom has an electron configuration of $1s^2 2s^2 2p^6 3s^1$. If the sodium atom becomes ionized, its new electron configuration will be the same as which element?
If the sodium is ionised, the outer $3s^1$ electron is lost, so the configuration becomes $1s^2 2s^2 2p^6$, which is the same as neon, $Ne$.
