Electrons are subatomic particles that are found in the energy levels of an atom. They are negatively charged and orbit around the nucleus of the atom. Electrons play a crucial role in determining the chemical and physical properties of elements, as their arrangement in energy levels determines the atom's reactivity and ability to form chemical bonds. Therefore, electrons are the correct answer to the question.

The electrons are the red dots that are around the nucleus of the atom.

Cesium is a chemical element with the symbol Cs. It is a soft, silvery-gold alkali metal. The symbol Cs is derived from the Latin word "caesius," which means sky blue, referring to the blue spectral lines that characterize the element. Cesium is highly reactive and has various applications in industries such as electronics, atomic clocks, and medical imaging.

The black dots are the electrons. They are around the nucleus of the atom in the electron clouds.

Ruthenium is the correct answer to the question. Ruthenium is an element on the periodic table with the symbol Ru. It is a transition metal and belongs to the platinum group. Ruthenium is known for its high corrosion resistance and is often used as a catalyst in various chemical reactions.

Neon has 10 protons because the atomic number of an element represents the number of protons it has. Neon has an atomic number of 10, which means it has 10 protons in its nucleus. Protons are positively charged particles and are one of the fundamental building blocks of an atom.

Bismuth is an element with atomic number 83, which indicates the number of protons in its nucleus. Therefore, Bismuth has 83 protons.

Protons and neutrons are found inside the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. These subatomic particles are responsible for the mass of the atom and are tightly packed together in the nucleus. Electrons, which have a negative charge, orbit around the nucleus in specific energy levels.

The atomic number on the Periodic Table of Elements indicates the number of protons and electrons in an atom. Protons are positively charged particles found in the nucleus of an atom, while electrons are negatively charged particles that orbit around the nucleus. The atomic number represents the unique identity of each element and determines its position on the periodic table. It is a fundamental property of an element and is used to understand the atom's structure and behavior.

Bromine, with atomic number 35, has 35 electrons. The atomic number represents the number of protons in an atom, and since atoms are electrically neutral, it also represents the number of electrons. Therefore, Bromine has 35 electrons.

Niobium, with an atomic number of 41, indicates the number of protons in its nucleus. Since atoms are electrically neutral, the number of electrons in an atom is also equal to its atomic number. Therefore, niobium has 41 electrons.

The proton number is the atomic number. Since there are 4 protons, the atomic number is 4. Making this atom: Beryllium

32 (atomic mass) - 16 (atomic number) = 16 neutrons

The electrons are the red dots that are around the nucleus of the atom.

Aluminum is the correct answer because it is the name of the element with the symbol Al. Aluminum is a chemical element with atomic number 13 and symbol Al. It is a lightweight, silvery-white metal that is widely used in various industries due to its low density and high corrosion resistance.

Gallium has 31 protons. This is because the atomic number of an element corresponds to the number of protons in its nucleus. Since Gallium is an element, its atomic number is 31, which means it has 31 protons.

The neutrons are the blue dots in the nucleus of the atom. They have no charge.

The element symbol for Antimony is Sb.

The neutrons are in the nucleus. They are the particles with no charge.

Lithium is a chemical element with the atomic number 3, which means it has 3 protons in its nucleus. Protons are positively charged particles found in the nucleus of an atom. Therefore, the correct answer is 3 protons.

Calcium is an element with atomic number 20, which means it has 20 protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons. Therefore, Calcium has 20 electrons.

Look at the number of protons. The number of protons is the atomic number of the element. This element has 9 p+. The atomic number is 9, so the element is Fluorine.

11 (atomic mass) - 5 (atomic number) = 6 neutrons

Hydrogen has one electron because it is the first element on the periodic table and has an atomic number of 1. The atomic number represents the number of protons in the nucleus of an atom, and since atoms are electrically neutral, it also represents the number of electrons. Therefore, hydrogen, with an atomic number of 1, has one electron.

35 (atomic mass) - 17 (atomic number) = 18 Neutrons

The number of neutrons in an atom can be calculated by subtracting the atomic number (which represents the number of protons in the nucleus) from the atomic mass (which represents the total number of protons and neutrons in the nucleus). This calculation gives the difference between the two, which corresponds to the number of neutrons in the atom.

51 (atomic mass) - 23 (Atomic Number) = 28 neutrons

The total number of protons and neutrons in an atom is referred to as the atomic mass or weight. This value represents the combined mass of the nucleus of the atom. The protons and neutrons are the two types of subatomic particles found in the nucleus, and their total number determines the atomic mass. The atomic mass is measured in atomic mass units (amu) and is an important characteristic of an element as it helps in identifying and classifying different atoms.

Dimitri Mendeleev is credited with creating the first Periodic Table of Elements. He organized the elements based on their atomic mass and properties, and left gaps for elements that were yet to be discovered. His periodic table was a significant breakthrough in the field of chemistry as it provided a systematic way of organizing and understanding the elements. Mendeleev's work laid the foundation for the modern periodic table that we use today.

Henry Mosley rearranged the Periodic Table and assigned each element an atomic number.
