Atoms Introduction (Extra Credit Work(

Front

The negatively charged particle that is found in the rings of an atom is called a(n)

Back

electron

Answer explanation

The negatively charged particle in an atom's rings is called an electron. Electrons orbit the nucleus and are essential for chemical bonding, while protons and neutrons are found in the nucleus and have positive and neutral charges, respectively.

Front

The nucleus is made up of

Back

Protons and neutrons

Answer explanation

The nucleus is composed of protons and neutrons, which are both types of nucleons. Electrons are found in the electron cloud surrounding the nucleus, not within it.

Front

The neutrally charged particle (no charge) inside the nucleus is called a(n)

Back

neutron

Answer explanation

The correct answer is 'neutron' because it is the neutrally charged particle found in the nucleus of an atom, unlike protons which are positively charged and electrons which are negatively charged.

Back

neutron

Answer explanation

The correct answer is 'neutron' because it is the neutrally charged particle found in the nucleus of an atom, unlike protons which are positively charged and electrons which are negatively charged.

Proton

Back

A positively charged particle in the nucleus

Answer explanation

A proton is a positively charged particle found in the nucleus of an atom. This distinguishes it from electrons, which are negatively charged and found in the outer regions, and neutrons, which are neutral.

Front

What is the mass number of this element?

Back

35

Answer explanation

The mass number of an element is the sum of its protons and neutrons. In this case, the correct mass number is 35, indicating the total number of these particles in the nucleus of the element.

Front

What element is this? Options: Argon, Chlorine, Iron, Nitrogen

Back

Chlorine

Answer explanation

Chlorine is a halogen and is represented by the symbol Cl. It is distinct from Argon (noble gas), Iron (metal), and Nitrogen (non-metal), making it the correct choice among the options provided.

Front

How many protons are in Beryllium?

Back

4

Answer explanation

Beryllium has an atomic number of 4, which means it has 4 protons in its nucleus. Therefore, the correct answer is 4.

Front

What atomic particle determines the element?

Back

protons

Answer explanation

Protons are the atomic particles that determine the identity of an element. The number of protons in an atom's nucleus defines which element it is, making protons the key factor in elemental classification.

Front

How are electrons arranged in an atom?

Back

In energy levels

Answer explanation

Electrons are arranged in energy levels around the nucleus of an atom. These levels represent different distances from the nucleus and can hold a specific number of electrons, making 'in energy levels' the correct choice.
