TRUE OR FALSE QUESTIONS 1) The physical properties of metals include
dullness, malleability, ductility, and conductivity.
2) Neutrons have a negative charge.
3) Mendeleev was known as the father of the
periodic table.

1: FALSE The physical properties of metals include shininess, malleability, ductility, and conductivity.

2: FALSE Neutrons are the particles in an atom that have a neutral charge. They aren't positive like protons. They aren't negative like electrons.

3: TRUE Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is best remembered for formulating the Periodic Law and creating a farsighted version of the periodic table of elements. He is also known as the "father of the periodic table"

Explanation:

2 is false because electrons have a negative charge neutrons have no charge
