Does the change in temperature of an object affect how much heat it can transfer to another object

The temperature of an object affects how much heat can be transferred. This is because if the object to which heat is transferred has high temperature then there will not be much heat transfer. Heat flows from a body of higher temperature to lower temperature.

What do elements with in a family tend to share

elements in the same family tend to share the same number of valence electrons. That is the number of electrons in the outer shell.
