What's an element in period 5 with larger radius than Yttrium?

1 answer:

7 0

Rubidium or strontium have larger a larger atomic radius since the further left on the periodic table you go, the larger the sizes of the atoms are. This trend can be explained through effective nuclear charge which explains how the further left and down you go, the less the atoms nucleus is able to pull in the electrons around it.<span />

The balanced equation for the neutralization reactions is as below.

<h3>Balancing chemical reaction equations</h3>

In order for chemical equations to be balanced, the number of atoms of each element before and after the reaction must be equal.

Thus:
