At about 3:02, an atom of Lithium loses an electron to an atom of Fluorine. Is this a chemical reaction? Why or why not? Why are there “+” and “-” signs on the elements after the electron is transferred? Need Help ASAP

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

that tool would be a compass

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

the awnser is group 12
