hope this helps

Part 1

Define matter, and an atom

Ans: An atom is the smallest unit of matter that retains all of the chemical properties of an element. matter is any substance that has mass and takes up space by having volume. Atoms are combine to form matter.

Define Protons, Neutrons, and Electrons

Ans: . Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral)

Identify the location of protons, neutrons, and electrons within an atom

Ans:Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus.

What is the mass and charge of a proton, neutron, and electron?

Ans: Protons, neutrons, and electrons: The nucleus contains protons and neutrons, each of which has a mass of one amu. Protons, on the otheAnsr hand, have a charge of +1, whereas neutrons are uncharged. Electrons have a charge of -1 and have a mass of around 0 amu. They orbit the nucleus and have a mass of approximately 0 amu

Define a cation and anion.

Ans:Cations are ions that are positively charged. Anions are ions that are negatively charged

Ans:Cations are ions that are positively charged. Anions are ions that are negatively chargedDraw the stable, Cation, and Anion versions of lithium and boron

How do you determine the mass and charge of an entire atom?

Ans: The mass of an atom is a weighted average that is largely determined by the number of its protons and neutrons, whereas the number of protons and electrons determines its charge. Each atom of an element contains the same number of protons, known as the atomic number (Z).

How do we use the periodic table? Identify periods and groups in a periodic table

Ans:The periodic table is arranged in order of atomic number. A period is a horizontal row of the periodic table. A group is a vertical row of the periodic table

What is the chemical symbol of an element? Atomic mass?

Ans: The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D).

Why is the atomic number of an element important? What information does the atomic number

provide us with?

Ans: The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the characteristic which makes each element unique compared to all other elements.

sorry can't fit part 2

I should get 100 points for this
