What elemental trend exists in each row as we move from left to right on the periodic table? number of protons decreases number of protons increases chemical reactivity of metals increases chemical reactivity of nonmetals decreases

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

What is the mass of each element in a 324.8 sample of co2

The table lists the lattice energies of some compounds. compoundlattice energy (kj/mol)lif            –1,036licl            –853naf            –923kf            –821nacl            –786which statement about crystal lattice energy is  best  supported by the information in the table? the lattice energy increases as cations get smaller, as shown by lif and kf. the lattice energy increases as the cations get larger, as shown by lif and licl. the lattice energy decreases as cations get smaller, as shown by nacl and naf. the lattice energy decreases as the cations get smaller, as shown by naf and kf.
