When sodium atoms form sodium ions they
share protons
gain neutron
lose elections
share photons

The correct answer is - Lose electrons.

An ion is an electrically charged particle that is formed by either loss of electron or gain of electron from a neutral atom.

The atomic number of sodium is 11. It electronic configuration is- 2, 8, 1

In order to achieve stable electronic configuration, it loses one electron from its valence shell and becomes positively charged ion that is cation.

Thus, to form sodium ion ( which is a cation), loss of one electron takes place.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
