How did Thomson determine that the electrons have a nucleus?
An electron and a neutron have different charges.
They repel each other.
The nucleus has protons and electrons inside.
An electron is attracted to a protons.
The mass of a neutron is twice that of a protons.
They repel each other.
The charges of electrons and neutrons are different.
When you brush your hair, it splits.
If the atomic number and mass number of an atom are given, then the number of protons, neutrons, and electrons should be stated.
The atoms of the same element have the same number of protons.
The feature distinguishes atoms of one element from atoms of all the other elements.
The atomic number is the whole number that appears above the symbol of the elements on the periodic table.
The periodic table on the inside front cover shows the elements in order of their atomic number.
An atomic number can be used to identify the number of protons in an atom.
An atom with atomic number 3 has 3 protons.
Any atom with 3 protons is a lithium atom.
A carbon atom with atomic number 6 has 6 protons.
Any atom with 6 protons is carbon.
The atom is neutral.
Every atom has an overall charge of zero, because the number of protons in an atom is equal to the number of electrons.
Every atom of barium has an atomic number.
The mass of the nucleus is determined by the protons and neutrons.
The mass number is not on the periodic table because it applies only to single atoms.
All the atoms of carbon have six protons and six electrons.
The mass number of the nucleus of an oxygen atom is 16.
An atom of iron has a mass number of 58.
We can calculate the number of neutrons in the nucleus if we know the mass number of the atom and its atomic number.
We can calculate the number of neutrons in the nucleus of an atom with a mass.
tABLE shows the relationships between atomic number, mass number, and the number of protons, neutrons, and electrons in examples of single atoms.
The proper functioning of the immune system, as well as the growth of bone, teeth, and connective tissue, are all dependent on Zinc.
Zinc has 30 protons and an atomic number of 30.
The mass number is used to find the number of neutrons in this atom.
The number of electrons is equal to the number of protons.
There is a zinc atom.
Try Practice Problems 4.29 to 4.32 Carbon has the symbol C. Since prehistoric times, two forms of carbon have been arranged as rings of five and six atoms.
When a fullerene structure is stretched out, pro diamond is transparent and harder than any other substance, whereas a cylinder with a diameter of only a few nanometers called a graphite is black and soft.
Buckyballs and nanotubes are not rigid structures.
Carbon atoms are arranged in flat sheets that oped, but they are expected to use in lightweight structural materi slide over each other.
