Molecular or covalent compounds

Non metals

How does a molecular compound compare to the elements that make up the compound?

The properties of a compound depend on the identity of the component elements, and not the chemical bonds they form.

Molecules are attracted to one another by Van der Waals forces. How do Van der Waals forces compare with ionic and covalent bonds?

Van der Waals forces are weaker than ionic and covalent bonds.

What number of mass does deuterium have

has a mass number of 2

atoms of an element..

have the same number of protons

Ionic

metal and nonmetal

Electron

negatively charged particle; located outside the atomic nucleus

Neutron

neutral charge, found in nucleus

Deuterium is an isotope of hydrogen. It has a mass number of two. Which describes a deuterium atom?

nucleus of one proton and one neutron, which is orbited by one electron

protons

positive charge, found in nucleus

All atoms have equal numbers of

protons and electrons

what happens when atoms approach one another

they may share or transfer their electrons

What is a molecule?

two or more atoms held together by covalent bonds

van der Waals

weak attractive forces between molecules when molecules are very close together

Molecular and covalent

-sharing of electrons

The atomic number of carbon is six, which means that a carbon atom has six protons. Carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. Which of these statements are true about carbon and its isotopes? Select all that apply.

All carbon atoms have six protons and six electrons. Atoms of some naturally occurring carbon isotopes may have six neutrons.

Deuterium

An isotope of hydrogen with one proton and one neutron in the nucleus having an atomic weight of 2.014

van der Waals forces

Are weaker than covalent and iconic forces that act within molecules

Ionic

Electrons get stolen and opposite changes attract

The atoms of isotopes

Have varying numbers of neutrons
