A neutral atom contains 12 neutrons and 11 electrons. The number of protons in this atom is

11

What is the atomic number of an element that has six protons and eight neutrons?

14

A sample of matter must be copper if

Each atom in the sample has 29 protons

Every chlorine atoms has

an atomic number of 17

All phosphorus atoms have the same

atomic number

Which quantity represents the number of protons in an atom?

atomic number

According to the modern model of the atom, the nucleus of an atom is surrounded by one or more

electrons

Two atoms will always have the same atomic number if they have the same

number of protons

An atom is electrically neutral because the

the number of protons equals the number of electrons

Compared tot he charge of a proton, the charge of a electron has

the same magnitude and the opposite sign

Compared to a proton, an electron has

the same quantity of change and the opposite sign

What can be determined if only the atomic number of an atom is known?

the total number of protons and the total number of electrons in the atom.
