What do elements across a series have the same number of?

What do elements across a series have the same number of?

electrons
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

What do elements in the same periodic table have in common?

The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.

What happens to elements as we go across the periodic table?

Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

In what way are elements in the same column of the periodic table the same?

In what way are elements in the same column of the periodic table the same? The elements in the same column of the periodic table are all part of the same chemical family or group. Each member of the chemical family has the same number of valence electrons.

Do elements in the same period have the same properties?

They exhibit similar chemical properties. Elements within the same period have different number of electrons in their valence shells (the number is increasing from left to right) and different valence shell electron configuration. Therefore, elements in the same period are chemically different.

What do these elements have in common?

The common feature is that the atoms of all elements consist of electrons, protons, and neutrons.

Which element would go on the left?

metals
The elements to the left of the stairs in the periodic table are called metals.

How do the elements change as you go to the right along a row of the periodic table?

Those to the right are non-metals. Next the atomic number and therefore the proton number increase as you move from left to right B – 5, C – 6, N -7. Also the Atomic Mass increases from left to right B – 10.81, C – 12.01, Atomic radius decreases moving left to right on the periodic table.

How do properties of elements in the same group of the periodic table compare?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

Why are some elements similar to others on the periodic table?

This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. However, there are also other patterns in chemical properties on the periodic table. For example, as we move down a group, the metallic character of the atoms increases.

How many elements are on the periodic table of elements?

All isotopes of an element fall under a single cell on the periodic table, since they all share the same atomic number. The table below consists of 118 elements of the periodic table, sorted by atomic number, atomic weight, symbols, density, discovered year and the group.

What are the rows on the periodic table called?

The periodic table is an arrangement of all the elements known to chemistry, according to particular patterns in the number of their electrons, protons, and neutrons. The columns of the periodic table are known as groups, and the rows are called periods.

Is the atomic number of an element always the same?

The atomic number of each element is unique. The combined number of protons and neutrons in an atom is called the atomic mass number. While the atomic number always stays the same some elements have atoms with different atomic mass numbers.
