A chemical formula shows the kind and number of Atoms that form a <span>compound</span>
An independent variable is the variable you are changing in order to measure the dependent variable, which is what you are measuring.
In this example, the
independent variable: chemicals in solution
dependent variable: temperature of solution
Answer:
It will lose 2 electrons
Explanation:
Here we have a calcium atom, which has 20 electrons.
Those 20 electrons are in 4 shells. (2-8-8-2)
Saying there are 2 electrons in the valence shell (Shell N), to get to an octet with an ionic bond (with a group 16 element), those 2 electrons will have to go.
