What are rows called in Periodic rable?
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
What element has a electron of 85?
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
What element in Group 1 has the largest atoms?
Cesium, which is in Group 1 of the periodic table, has the largest atoms. This is because as you move down a group, the atomic size generally increases due to the addition of more electron shells.
What is the characteristics about the outer electron shells of halogens?
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
How many shells of electrons are there in element 53?
since it is in period 5 it contains 4d and 3d levels which both hold 10 electrons each. so therefore I (53) has 20 d electrons
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
How many electrons shells does Platinum have?
Platinum is in the 6th period, meaning its atom has 6 energy shells. It is in Group 10 and has 78 electrons.
Which way does electron shells increase on the periodic table?
The number of shells in periodic table increase down the group, i.e., vertically.
What element is in group 7 and has 5 energy shells?
The element is iodine (I). It is in group 7 of the periodic table and has 5 energy shells.
What are rows called in Periodic rable?
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
What do the horizontal rows on the periodic table represent?
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
What element has a electron of 85?
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
The period on the periodic table tells you what?
The group to which the element belongs and, therefore, its chemical properties.
An element from group eighteen from the periodic table is?
An element from group eighteen from the periodic table is commonly referred to as a "noble" or "inert" gas. These elements have filled electron shells, and therefore they do not share, take or give away any electrons. As a group they do not react with othere elements to form compounds (with only a couple of rare exceptions).
What are the groups on the periodic table and how do they relate to the periodic period of elements?
The groups on the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
Which element has an atomic number of 45?
The element with atomic number 45 is Rhodium (Rh). Rhodium is a transition metal in Group 9, Period 5 of the Periodic Table. Rhodium has 45 electrons in 5 electron shells with 1 electron in the outer shell.
Is na an element?
Yes. Na is the chemical symbol for Sodium. Sodium is an Alkali Metal in Group 1 of the Periodic Table. Sodium has the atomic number 11, has 3 electron shells with 1 electron in the outer shell.
