The nucleus contains protons, which have a positive charge equal in magnitude to the electron's negative charge . The nucleus may also contain neutrons, which have virtually the same mass but no charge.
What do you think is the charge of the nucleus of an atom Brainly?
It has a charge of -1 , exactly equal and opposite to that on the proton. In any complete atom, the number of protons in the nucleus is precisely equal to the number of electrons orbiting it; meaning that the atom's total charge is equal to zero.
What is the charge of the nucleus Why?
The nucleus has an overall positive charge as it contains the protons . Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
What is the charge of the nucleus of an atom quizlet?
What is the charge of the nucleus? Number of protons is equal to the number of electrons . Explain why atoms are electrically neutral. Overall charge is neutral since electrons are distributed evenly.
Does nucleus have positive charge?
The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons , which have a positive charge equal in magnitude to the electron's negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.
What was Rutherford's model called?
Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom , description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford.
What indicates that an atom has no overall charge?
An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges, this means that atoms are have no overall electrical charge.
Why does an atom have no net charge?
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral . ... Protons and neutrons have nearly equal masses, but they differ in charge.
What is an atom's nucleus made of?
The nucleus is a collection of particles called protons , which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.
How big is the nucleus of an atom?
The diameter of a nucleus is about 2 × 10 – 15 m and the diameter of an atom is 1 × 10 – 10 m.
What is the net charge of the nucleus?
Explanation: A nucleus is made up of protons and neutrons. Protons have a positive charge and neutrons have a neutral charge. Since a neutral charge won't cancel out a positive charge, the overall charge of a nucleus is positive .
Is the nucleus mostly empty space?
There is no empty space around a nucleus , as in Bohr's superseded model. ... The nucleus makes up a tiny proportion of the space occupied by an atom, while the electrons make up the rest.
What particle has no charge?
Neutron , neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10 − 27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
Do atoms contain empty space?
In reality, atoms do not contain any empty space . Rather, they are filled completely with spread-out electrons, making the shrinking of atoms impossible.
What force holds the nucleus together?
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
