Where are the alkali metals, the alkaline earth metals, the halogens, and the noble gases located on the periodic table?
ivolga24 [154]
The Alkali Metals- (Group 1A)can be found (excluding hydrogen) in the first column of the periodic table. They all have 1 valence electron and tend to form +1 cations when forming Ionic bonds with non metals. 

The Alkali Earth Metals: (Group 2A) can be found in the second column/group on the periodic table. These elements form +2 positively charged cations when forming Ionic bonds with non metals. They also all have 2 valence electrons. 

The Halogens: are the elements that make up the second to last group on the periodic table. These elements include Chlorine, Fluorine, Bromine, Iodine, and Astatine. These elements have 7 valence electrons. The usually form a -1 charged anion when forming ionic bonds with metals. 

The Noble gases: the very last group on the periodic table. All these elements have 8 valance electrons. Due to the octet rule these atoms are already very stable and rarely react with other elements.

The Prandtl number, Npr, is a dimensionless group important in heat transfer calculations. It defined as Cuk, where C, is the he
VARVARA [1.3K]

Answer:

The Prandlt number for this fluid is 1630.

Explanation:

The Prandlt number is defined as:

Pr=\frac{C_p\mu}{k}

To compute the Prandlt number for this case, is best if we use the same units in every term of the formula.

\mu=1936\frac{lb}{ft*h}*\frac{1000g}{2.205lb}*\frac{3.281ft}{1m}*\frac{1h}{3600s}  \\ \\\mu=800 \frac{g}{m*s}

Now that we have coherent units, we can calculate Pr

Pr=\frac{C_p\mu}{k}=\frac{0.583*800}{0.286}= 1630

How many electrons are shared by a triple <br> bond?
alekssr [168]

Answer:

6

Explanation:

6 electrons

Every covalent bond is a sharing of two electrons between two atoms. A double bond is 4 electrons being shared (2x2). Therefore a triple bond is 6 electrons being shared (2x3). Hope this helps!
