Answer:

The elements are Tin (Sn) and Lead (Pb)

Explanation:

They are 4+ and 2+

For the 2+, this happens because of the loss of the outermost two P electrons and for the 4+, because of the loss of two electrons from the P orbital and another two electrons from the s-orbital.

Elena held a rock weighing 1 N in her hand. The rock has no velocity. <br> KE________?

nignag [31]

KE = 0

<h3>Further explanation </h3>

Energy is the ability to do work

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:

$\large{\boxed{\bold{KE=\frac{1}{2}mv^2}}}$

So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy

The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy

But this stone can have <em>potential energy that is gained due to its height</em>
