What is the atomic number of titanium? How many protons does a titanium atom have? How many electrons does it have?
The correct answer and explanation is:
The atomic number of titanium (Ti) is 22.
A titanium atom has 22 protons in its nucleus. This is because the atomic number of an element is equal to the number of protons in the nucleus of its atom. Since titanium has an atomic number of 22, it contains 22 protons.
In a neutral atom, the number of protons is balanced by an equal number of electrons. Thus, a neutral titanium atom also has 22 electrons. Electrons are negatively charged particles that orbit the nucleus of the atom. These electrons are arranged in energy levels or shells around the nucleus, and their number is always equal to the number of protons in a neutral atom.
The number of protons determines the identity of the element, so any atom with 22 protons will always be titanium. The number of electrons in a neutral atom is also 22. However, if titanium were to gain or lose electrons, it would become an ion. For example, if titanium lost two electrons, it would have a +2 charge, becoming a Ti²⁺ ion.
The atomic number is essential because it defines the chemical properties of the element and its position on the periodic table. The number of protons, electrons, and the arrangement of electrons influence how titanium reacts with other elements. Titanium is a transition metal, and it has properties such as high strength and resistance to corrosion. These properties are influenced by its electron configuration, especially the electrons in the outermost shell.
