Enter the number of electrons in each energy level (shell) for each of the elements. If the energy level does not contain any electrons, enter a 0. It may help to refer to the periodic table. C:
=1

=2

=3

=4

S:
=1

What is the neutral atom that has its first two energy levels filled, has 4 electrons in its third energy level, and has no other electrons? Enter the name of the element, not the abbreviation.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
