Chemistry Chapter 4 & 5 (2019)

Responsible for an atom's chemical properties

Lead has this many neutrons

Father of Modern Chemistry

First to state that matter is made of atoms

Elements in this group do not combine regularly with other elements

T/F: Principal energy level 1 has one s orbital, 2 has two s orbitals, 3 has three, and so on.

An atom will form a(n) _____ by losing electrons

The Gold Foil experiment led to the discovery of these

Magnesium with a charge of +2 has this many electrons

T/F: Calcium "wants" to achieve the Argon noble gas configuration

Discovered neutrons

This particle makes the greatest contribution to an atom's mass

The correct electron configuration of Silicon is

First to organize the elements into the periodic table

Electromagnetic radiation can be found in all of the following except...

If a particle contains 12 protons and 10 electrons, then....

Gold Foil experiment

The relationship between wavelength and frequency is the following:

T/F:Light is given off by electrons of atoms only while being excited to a higher energy level.

Electrons, protons, and neutrons are these kind of particles

He developed the electron cloud model that shows orbitals

How many oxygen atoms in Be(NO₃)₂?

True/False: Charge of +1, mass of 27 amu = contains 13 protons, 14 neutrons, and 10 electrons

When atoms absorb energy, they achieve this state

An “f”sublevel can hold up to 8 electrons
