1

In which type of compound are electrons shared between atoms?

56% Answer Correctly

ionic

covalent

molecular

chemical
Solution

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.

2

Molecules and atoms that are outputs from a chemical reaction are known as which of the following?

57% Answer Correctly

results

reactants

side effects

products
Solution

During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).

3

Elements that belong to the same period in the Periodic Table of the Elements have the same number of:

50% Answer Correctly

atomic mass units

protons

electrons

electron shells
Solution

The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number. 

4

In the heart, the __________ artery and vein manage blood flow to the lungs.

69% Answer Correctly

atrial

pulmonary

capillary

aorta
Solution

The two largest veins in the body, the venae cavae, pass blood to the right ventricle which pumps the blood to the lungs through the pulmonary artery. Blood picks up oxygen in the lungs and returns it to the left atrium via the pulmonary vein.

5

In which type of compound does one atom borrow an electron from another atom?

58% Answer Correctly

covalent

ionic

acidic

chemical
Solution

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
