Element and compound Quiz

The three basic components of an atom are

• protons,neutrons and ions

• protons, neuron and electrons

• protons, neutrinos

• protium, deuterium and tritium

An element is determined by the number of:

• atoms

• electrons

• neutrons

• protons

The nucleus of an atom consists of:

• electrons

• neutrons

• protons and neutrons

• protons, neutrons and electrons

A single proton has what electrical charge?

• no charge

• positive charge

• negative charge

• either a positive or negative charge

A single electron has what electrical charge?

• no charge

• positive charge

• negative charge

• either a positive or negative charge

The atomic number of an atom is

• the number of atoms

• the number of neutrons

• the number of electrons

• the number of protons plus the number of electrons

The mass number of an atom is

• the number of electrons

• the number of neutrons

• the number of protons

• the number of protons plus the number of neutrons

An elements is formed by:

• sharing of outer most electrons

• transferring of electrons from the outer most shell from one atom to the other atom accepting the electrons onto it outer most shell

• sharing of electrons from the first shell

• transferring of electrons from the inner most shell from one atom while the other atom accepting the electron onto it inner most shell

A compound is formed by:

• sharing of outer most electrons

• transferring of electrons from the outer most shell from one atom while the other atom accepting the electron onto it outer most shell

• sharing of electrons from the first shell

• transferring of electrons from the inner most shell from one atom while the other atom accepting the electron onto it inner most shell

When an atom loses it outer most electron, the ion stage of the atom is:

• positive

• negative

• positive & negative

• remain neutral
