Atomic Structure

The superscript represents

The weighted average of the atomic masses of naturally occurring isotopes

Short-range forces that hold nuclear particles together

Located inside the nucleus.

The number of what determines the atom's identity?

Most of the atom is made up of empty space

The nucleus is made up of protons and neutrons.

What is this

The atom is neutral

This is how I feel about the atomic structure test

Standards of measurement of constant o the same everywhere

Molar mass is equal numerically to

If the atom was the size of a football stadium, the nucleus would be the size of

The following is an example of

An isotope written with a nuclear symbol has a superscript that represents

Located in orbitals found within energy levels outside the nucleus

The atom is neutral in nature.

The number of protons and number of electrons are equal in an atom

Avogadro's number is

mass number

atoms of the same element that have different masses

The hyphen notation is used when?

The smallest particle of an element that retains the chemical properties of that element

The atomic number is also equal to the number of

Identify the photo

The purpose of neutrons is to

Has a relative mass of 0 amu

The electron cloud is very small and extremely dense

Negatively charged particle

One mole contains as many particles as there are atoms in how many grams of carbon-12?

The equation to calculate molar mass is

Electrically neutral

Has a relative mass of 1 amu

All the mass of an atom is equally distributed.

Positively charged particle

Isotopes have the same number of protons and electrons but different

Can be broken down into three smaller subatomic particles

All of the positive charge is concentrated in the electron cloud

What is Avogadro's number used for?

Which of the following has a relative charge of -1?
