Which of the following is an example of convection? A. a hot oven warming the air around it

B. the rays of sun warming the earth

C. hot air rising and cooler air failing

Explanation:

Loosely bound d electrons.

Explanation:

These elements are very hard, with high melting points and boiling points. Moving from left to right across the periodic table, the five d orbitals become more filled. The d electrons are loosely bound, which contributes to the high electrical conductivity and malleability of the transition elements.
