What else can I help you with?
Which characteristics both generally decrease When the elements in period 3 on the periodic table are considered it order from left to right?
As you move from left to right across period 3 on the periodic table, the atomic radius, metallic character, and reactivity generally decrease. This is because the increasing number of protons in the nucleus leads to stronger attraction for the electrons, resulting in a smaller atomic size and less metallic behavior.
What is the arragenment of all the known elements in order of their atomic numbers?
The arrangement of all known elements in order of their atomic numbers is called the periodic table of elements. The periodic table organizes elements based on increasing atomic number, showing similarities in properties and periodic trends across rows and columns.
What factors contribute to the decrease in atomic radius as you move across a period on the periodic table?
The decrease in atomic radius as you move across a period on the periodic table is primarily due to increasing nuclear charge and the attraction between the positively charged nucleus and the negatively charged electrons. This stronger attraction pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
What are periodic trends?
Periodic trends are patterns that are observed as you move across or down the periodic table of elements. These trends include atomic radius, ionization energy, electronegativity, and metallic character, among others. They help predict the properties of elements based on their position in the periodic table.
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
Why does atomic size tend to decrease with increasing atomic number across a row of the periodic table?
electronegativity
What happens to the radii of the elements between 2 highest peaks?
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
What goes across the periodic table?
The periodic table is arranged by increasing atomic number, which moves from left to right across each row. As you move from left to right across a row, the elements increase in atomic number and atomic mass, with similar chemical properties grouped together.
When you go across the periodic table how does the atomic size go?
Atomic size tends to decrease as you move from left to right across a period on the periodic table. This is due to increasing effective nuclear charge, which attracts the electrons more strongly and pulls them closer to the nucleus.
How much does the number increase by as you go across a row on the periodic table?
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.
Which characteristics both generally decrease When the elements in period 3 on the periodic table are considered it order from left to right?
As you move from left to right across period 3 on the periodic table, the atomic radius, metallic character, and reactivity generally decrease.

The decrease in atomic radius as you move across a period on the periodic table is primarily due to increasing nuclear charge and the attraction between the positively charged nucleus and the negatively charged electrons.

What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
