How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?
17 electrons. The number of protons and electrons is always the same.
If a neutral atom contains 18 protons how many electrons does it contain?
A neutral atom contains the same number of electrons as protons. Therefore, an atom with 18 protons will also have 18 electrons to maintain an overall neutral charge.
An atom has 15 protons and 18 neutrons How many electrons does it have?
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
Number of electrons in argon?
In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is 18; therefore, each atom contains 18 electrons.
How do you know how many electrons argon has?
Argon has 18 electrons because it possesses 18 protons in its nucleus, making it electrically neutral. The number of electrons in an atom is equal to the number of protons in the nucleus.
How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?
17 electrons. The number of protons and electrons is always the same.
If a neutral atom contains 18 protons how many electrons does it contain?
A neutral atom contains the same number of electrons as protons. Therefore, an atom with 18 protons will also have 18 electrons to maintain an overall neutral charge.
An atom has 15 protons and 18 neutrons How many electrons does it have?
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
An atom has what number of protons and electrons?
9 protons and 10 neutrons in F-19 isotope.
Number of electrons in argon?
In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is 18; therefore, each atom contains 18 electrons.
How many protons and electrons does chlorine have?
Chlorine has: 17 Protons 17 Electrons (in a neutral atom i.e. not an ion) (Isotope Mass Number - 17) is the number of Neutrons.
How do you know how many electrons argon has?
Argon has 18 electrons because it possesses 18 protons in its nucleus, making it electrically neutral. The number of electrons in an atom is equal to the number of protons in the nucleus.
How many protons and electrons does a chloride ion have?
Protons = 17, electrons = 18There are two isotopes differing in neutron number only :Cl-35 (75%) having 35-17= 18 neutronsCl-37 (25%) having 37-17= 20 neutrons
How many protons and electrons are in one atom of chlorine?
One atom of chlorine contains 17 protons and 17 electrons. The number of protons determines the element's identity, while the number of electrons balances out the positive charge of the protons to keep the atom electrically neutral.
How many protons and electrons does argon have?
i will say 18 neutrons and electrons
How is the charge of the atom or ion determined from the number of protons neutrons and electrons present?
Atoms have protons, neutrons, and electrons. Protons and electrons have electric charge, but neutrons do not. Protons are positively charged, and electrons are negatively charged. An atom has the same number of protons and electrons. Because the atom has same amounts of positively and negatively charged particles, the atom is neutral and has no electric charge. The only time an atom becomes electrically charged is if it loses or gains protons or electrons to throw off the balance. For example, we know that hydrogen only has 1 proton, 1 neutron, and 1 electron. This hydrogen atom has not electric charge. Later on, the hydrogen atom gains a proton. This would mean that there is more positive charge than negative charge in the atom. The hydrogen atom is now electrically charged.
How many electrons are in argon - 40?
Argon-40 has 18 electrons. This is because argon has an atomic number of 18, which indicates the number of protons (and electrons) in a neutral atom of argon.
