Quarterly Assessment #1

Unit 0

100

Name the four proper safety attire that I should hold myself to when conducting a lab in class with an open flame and glassware.

Goggles, Closed toe shoes, tie hair back, baggy sleeves/jewelry

200

this substance can be separated by physical means

What is a mixture

300

This substance cannot be separated by ordinary chemical or physical means

What is an element

400

Wood is an example of this type of substance

What is a heterogenous mixture

500

This classification of property/change has the ability to alter the substance

What is a chemical property

Unit 1

100

These are the two particles that you would add to calculate the atomic mass

What are Protons and neutrons

200

This information about an element will never change no matter what

What are the number of protons

300

The atom I am working with has a recorded mass of 15 but another scientist has the same element and their mass is recorded as 16. I know that neither one of us made a mistake so we must be working with the same elements that have different masses also known as these.

What are isotopes

400

This is the charge of an atom with 14 protons 15 neutrons and 13 electrons

What is a +1 charge

500

I forgot to do what if the average mass of an atom I calculated comes out to 11,452 amu

What is convert my percentages to a decimal value

Unit 2

100

This is how I can display the valence electrons and show how an element will react

What is a Lewis Dot Structure

200

This color of the visual light spectrum has the lowest wavelength

What is violet light

300

This is the number of occupied energy levels for the element Titanium

What is 4 energy levels

400

This is the typical charge that the element in the 3p⁴ location will have

What is -2

500

This is the electron configuration for the element Gallium

What is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p¹

Unit 3

100

This family contains the most reactive nonmetals

What are the Halogens

200

This element has the largest atomic radius of any element

Francium

300

This trend does not include the elements with 8 valence electrons

What is electronegativity

400

Elements of the alkaline earth metal family will typically take on this ionic charge

What is +2

500

This is the reason that atomic radius decreases across a period

What is the increase in the magnetic attraction of the greater number of protons in the nucleus

Unit 4

100

This is the nuclear reaction that is responsible for the atomic bomb

What is Fission

200

This type of nuclear decay is the safest to work with and helped scientists to discover that the atom has a nucleus that is surrounded by empty space

What is alpha decay

300

This is the nuclear reaction that requires more and more heat and pressure the larger the elements are

What is Fusion

400

This is the type of nuclear decay that can transform the nucleus without affecting the mass

What is beta decay

500

This type of nuclear decay is accompanied by other types of decay and helps stabilize the nucleus of an atom by releasing energy

What is gamma decay
