Conserve hot water.. check on the heating system and the water heater..
Three factors that determine the reactivity of elements are the
valence electrons are the electrons in the outermost electron shell of an atom.
The number of electrons in an atom's outermost valence shell governs its
bonding behaviour. That is why in periodic table the elements were put together
according to their numbers of valence electrons.
METALS
The most reactive kind of metallic element is a metal from
Group 1 sodium or potassium.
An atom in Group 1 has only one valence electron.
NON-METALS
A nonmetal tends to attract another valence electrons to
attain a full valence shell.
The answer is : D)
It attracts Us but it is not strong enough for us to feel it. That is because we are too far away. If we were closer to Mars, we would be able to feel the force of attraction.
Hope this helped.
the answer is conduction mark me <u><em>branlest</em></u> please
