Its between the two hydrogen atoms (C) i hope i helped you guys out a bit.!
Puede tomar los valores enteros positivos: n= 1, 2, 3, 4, 5, 6, 7. Por ejemplo si tengo un elemento químico que su último nivel es el 3s, su número cuántico principal sería el 3. Si tengo un elemento químico en que su último nivel es el 1s, entonces su número cuántico principal sería 1.
Hey there! :
Mass = 156 g
Volume = 20.0 mL
Therefore:
Density = mass / volume
Density = 156 / 20.0
Density = 7.8 g/mL
Answer:
"Electronegativity" decrease moving from the bottom of Group 3 to the top of Group 3
Explanation:
Electronegativity of an element tell us about the ability of an atom to attract the electrons towards the atom. It depends upon the atomic number and also the distance between the valence electrons that is present in the charged nucleus. The electronegativity will increase from left to right while moving in the periodic table. Electronegativity decreases from bottom to top. To measure the electronegativity pauling scale is used.
