Chapter 3: Problem 5

In terms of period and group where would you locate the element with \(Z=114 ?\)

Short Answer

Expert verified
Flerovium (Z=114) is located in period 7, group 14.

Step by step solution

01

Identify the Atomic Number

The atomic number \(Z\) represents the number of protons in an atom's nucleus. Given \(Z = 114\), we identify that the element is flerovium (Fl). This step requires checking a periodic table for the element with atomic number 114.
02

Determine the Period

The element flerovium, with \(Z = 114\), needs to be placed in the right period. Elements in the periodic table are arranged into periods (rows). Flerovium is located in period 7, as elements with atomic numbers from 104 to 118 are part of this row.
03

Determine the Group

Next, determine the group of flerovium. Elements are also organized into groups (columns) in the periodic table. Using your periodic table, you find flerovium in group 14, the same group as carbon, silicon, and lead.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Atomic Number
The atomic number, often symbolized as "Z," is a fundamental characteristic of any element. It defines the number of protons in the nucleus of an atom, which in turn determines the element's identity. For instance, an element with an atomic number of 114 is flerovium.

The atomic number is crucial in distinguishing one element from another. Unlike protons, the number of neutrons and electrons can vary, leading to isotopes and ions, respectively, but the atomic number remains constant for each element.
  • Each element has a unique atomic number.
  • The atomic number is always a whole number.
  • In a neutral atom, the atomic number is equal to the number of electrons.
Recognizing that each element is defined by its atomic number helps you locate it on the periodic table since elements are arranged in order of increasing atomic number.
Periods in Periodic Table
The periodic table is structured into rows known as periods. Each period represents a new principal energy level that electrons are filling. As you move across a period from left to right, the atomic number increases, and so do the number of electrons and protons.

Flerovium, with an atomic number of 114, is found in period 7 of the periodic table. This period contains elements with atomic numbers ranging from 104 to 118, indicating that their valence electrons occupy the same outer electron shell.
  • There are 7 periods on the standard periodic table.
  • Period numbers increase as you move down the table.
  • The first element of a period signifies a new electron shell.
Understanding periods is essential for grasping how electrons are arranged around an atom's nucleus, which affects the element's chemical properties.
Groups in Periodic Table
In addition to periods, the periodic table is divided into columns known as groups. Elements within the same group typically share similar chemical properties due to having the same number of electrons in their outermost shell.

Flerovium is in group 14 of the periodic table, along with elements like carbon, silicon, and lead. Each of these elements has four electrons in its outermost electron shell, which explains some of their shared characteristics.
  • There are 18 groups in the periodic table.
  • Groups are numbered from 1 to 18.
  • Elements in the same group often exhibit similar reactions.
By understanding groups, you can predict how different elements might react chemically based on their position in the periodic table.
