How do you know what the charges are for any atoms on the periodic table?
The charges of atoms on the periodic table are determined by the number of protons and electrons they have. Protons carry a positive charge (+1) and electrons carry a negative charge (-1). The charge of an atom is balanced by the number of protons, which equals the number of electrons in a neutral atom.
Atoms in the same group on the periodic table have what?
Atoms in the same group (in the same vertical column) of the periodic table have the same number of electrons in their outer shell. A neutral atom has the same number of electrons as it has protons. The number of protons is given by it's atomic number. The electrons are considered to be arranged in "shells." The outermost shell can have from 1 to 8 electrons. The effect of being in the same group is that the atoms within a group have similar reactions.
What group in the periodic table has two valence electrons in their atoms?
The alkaline earth group has two valence electrons.
Can atoms have an expanded octet?
Yes, atoms beyond the second period in the periodic table can have an expanded octet, allowing them to hold more than eight electrons in their outer shell.
Why do atoms tend to get smaller as you move across the periodic table?
As you move across the periodic table, atoms tend to get smaller because the increasing number of protons in the nucleus pulls the electrons closer to the center, resulting in a stronger attraction and a smaller atomic size.
Where are atoms that tend to gain electrons located on the periodic table?
Atoms that tend to gain electrons are located on the far left side of the periodic table.
How are ions different from Atom?
Atoms are neutral on the Periodic Table. Ions consist of more or less electrons than atoms.
Where on the Periodic Table are atoms with 8 outer shell electrons located?
a
What do atoms of elements in the same group of the periodic have in common?
number of valence electrons
What does groups in a periodic table have?
atoms in a group have the same number of valence electrons
Do all elements of the periodic table have the same type of atoms?
No. Atoms differ in number of protons, neutrons and electrons.
How did Mendeleev create the periodic table when he knew nothing about electrons and atoms?
he read about it in the newspaper
When trying to predict the location and motion of electrons in atoms scientists must work with?
They use a Periodic Table.
What has role in neutrons changing into protons and electrons into unstable atoms?
strong force
How many electrons does sulfur have according to the periodic table?
Just so you know, the periodic table does not give any indication of how many electrons an atom has but 95% of sulfur atoms are neutral and so contain 16 electrons.
What do electrons and neutrons and prontons have to do with the elementes in the periodic table?
Elements are made of one type of atom. Atoms are made of electrons, neutrons and protons
How do you know what the charges are for any atoms on the periodic table?
The charges of atoms on the periodic table are determined by the number of protons and electrons they have. Protons carry a positive charge (+1) and electrons carry a negative charge (-1). The charge of an atom is balanced by the number of protons, which equals the number of electrons in a neutral atom.
