What else can I help you with?
Why does not the nucleus attract the atoms from top to bottom in a periodic table?
Down a group, the number of shell increases and the electron enters into a different shell. Hence, the distance between the nucleus and valence electron increases and the nuclear attraction decreases
What sentence can you make using the words periodic table and nucleus?
Some elements in the periodic table have a nucleus that is surrounded by a cloud of electrons with a negative charge. This is one sentence using nucleus and periodic table.
The order of element in the periodic table is base on what?
The order of elements in the periodic table is based on their atomic number, which is the number of protons in the nucleus of an atom. Elements are arranged in order of increasing atomic number from left to right and top to bottom on the periodic table.
What feature of atoms determines the order of the periodic table?
The number of protons in the nucleus of an atom, which is the atomic number, determines the order of the periodic table. Atoms are arranged in increasing atomic number from left to right and top to bottom in the periodic table.
What happen to the atomic as you from the bottom to the top of the periodic table?
As you move from the bottom to the top of the periodic table, the atomic size decreases. This is because the number of protons in the nucleus increases, leading to a stronger pull on the electrons. Electrons are added to the same energy level while moving up the table, resulting in a smaller atomic radius.
Where is lanthanum located on the periodic table?
Lanthanum is located on the right to the bottom side on the periodic table.
What are the energy levels doing on a periodic table when going from top to bottom?
the energy level increases as we move from top to bottom in the periodic table
Electronegativy from top to bottom on the periodic table?
Electronegativity generally decreases from top to bottom on the periodic table. This is because as you move down a group, the valence electrons are in higher energy levels, farther away from the nucleus, which reduces the attraction for additional electrons.
Does electronegativity increases from left to right across each row of the periodic table and also increases down each column?
Electronegativity generally increases from left to right across each row of the periodic table because atoms have more protons in the nucleus, increasing their ability to attract electrons. Electronegativity also tends to decrease as you move down each column because the distance between the nucleus and outer electrons increases, reducing the nucleus' pull on electrons.
Is f and d the center and bottom blocks of the periodic table?
D block elements are at the center of the periodic table; f block elements are at the bottom.
Were are the lanthanides placed on the periodic table?
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
Where are the antinides on the periodic table?
Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.
