The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
Polyethene is a polymer composed of repeating units of the monomer ethene.
The properties of polyethene are as follows:
- density- ranges 0.857 g/cm3 to 0.975 g/cm3.
- specific heat capacity is 1.9 kJ/kg.
- melting temperature is approximately 110 °C.

The answer is B. Limiting factors can lower birth rates, increase death rates.
NH3-The limiting reactant is the reactant that get completely used up in a reaction
Answer:
6
Explanation
every p sublevel holds up to 6 electrons
so the 4p sublevel must hold up to 6 electonsr
