Write the name and symbol of the element with the following atomic number: (4.1, 4.2)h. 92

Verified step by step guidance

1. Identify the atomic number given in the problem, which is 92.
2. Recall that the atomic number of an element corresponds to the number of protons in the nucleus of an atom of that element.
3. Use the periodic table to find the element with atomic number 92.
4. Note that the periodic table is organized by increasing atomic number, so locate the element in the table.
5. Write down the name and symbol of the element that corresponds to atomic number 92.

Key Concepts

Atomic Number

The atomic number of an element is the number of protons found in the nucleus of its atoms. It uniquely identifies an element and determines its position in the periodic table. For example, an atomic number of 92 corresponds to uranium, which has 92 protons.

Element Symbol

Each chemical element is represented by a unique one- or two-letter symbol, derived from its name. These symbols are used universally in chemical equations and formulas. For instance, the symbol for uranium is 'U', which is derived from its name.

Periodic Table

The periodic table is a tabular arrangement of elements organized by increasing atomic number. It groups elements with similar properties into columns, known as groups or families. Understanding the layout of the periodic table helps in identifying elements based on their atomic number and predicting their chemical behavior.
