Unit 3 Check In on Electrons

Front

What is an orbital?

Back

An orbital is a region in an atom where there is a high probability of finding an electron.

Front

What is the excited state electron configuration of Bromine?

Back

The excited state electron configuration of Bromine is 2-8-17-8.

Front

How do you determine the net charge of an ion?

Back

The net charge of an ion is determined by subtracting the number of electrons from the number of protons. For example, an ion with 10 electrons and 11 protons has a net charge of 1+.

Front

What is the Plum Pudding Model of the atom?

Back

The Plum Pudding Model is a model of the atom developed after J.J. Thompson discovered electrons, depicting electrons floating freely in a positive space.

Front

What is a possible excited state electron configuration for Silicon?

Back

A possible excited state electron configuration for Silicon is 2-8-3-1.

Front

What is the charge of an electron?

Back

The charge of an electron is -1.

Front

What is the charge of a proton?

Back

The charge of a proton is +1.

Front

What is the atomic number of an element?

Back

The atomic number of an element is the number of protons in its nucleus.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion (more protons than electrons), while an anion is a negatively charged ion (more electrons than protons).
