What contains positive and neutral particles?
An atom contains positively charged protons, neutral neutrons, and negatively charged electrons. Positively charged ions in a solution also contain positive and neutral particles, as they have lost electrons to become positively charged.
Is helium atom electrically neutral?
Yes, a helium atom is electrically neutral because it has an equal number of protons, which carry a positive charge, and electrons, which carry a negative charge. The positive charge of the protons cancels out the negative charge of the electrons, leading to a net charge of zero.
When a neutron star is formed what particle is produced by the combining of the protons and electrons?
When a neutron star is formed, protons and electrons are crushed, they collide and become neutrons.
What does neutral atom have equal number of?
a neutrally charged atom has an equal number of both protons and neutrons, making the positive and negative charges the same. for example, in a neutrally charged atom, there would be 1 neutron and 1 proton.
Is nitrogen a isotope ion or nuteral atom?
Nitrogen doesn't start out as a cation/anion, but it is in group 5A, so it has five valence electrons. To become stable (have a complete octet), it either has to lose five electrons or gain three. It is easier to gain three, so it gains three and becomes a 3- anion.
If an atom has 19 protons and 20 neutrons how many electrons would it have?
Electrons carry a negative charge and protons carry a positive charge. Therefore, if an atom is to be neutral it must have equal numbers of protons and neutrons. Consequently, if an atom has 19 protons and is neutral it must have 19 electrons.
How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
What happens when a neutral atom becomes positive?
the excess protons pull harder on the fewer neutrons
What contains positive and neutral particles?
An atom contains positively charged protons, neutral neutrons, and negatively charged electrons. Positively charged ions in a solution also contain positive and neutral particles, as they have lost electrons to become positively charged.
Does the sum of the protons in an atom equal the sum of the electrons?
Protons minus neutrons doesn't mean anything in chemistry. Protons plus neutrons gives the mass number. Protons minus electrons gives you the charge of an atom(ion). The number of protons are equal to the number of electrons in a neutral atom and the proton number is equivalent to the atomic number.
Is helium atom electrically neutral?
Yes, a helium atom is electrically neutral because it has an equal number of protons, which carry a positive charge, and electrons, which carry a negative charge. The positive charge of the protons cancels out the negative charge of the electrons, leading to a net charge of zero.
When a neutron star is formed what particle is produced by the combining of the protons and electrons?
When a neutron star is formed, protons and electrons are crushed, they collide and become neutrons.
Is the number Protons the same as electrons?
Yes.# of protons = # of electrons = atomic #Ex. K (Potassium) = atomic #: 19# of protons: 19# of electrons: 19They are in an uncharged or unionized atom. For example carbon (C) has 6 protons and 6 electrons the cation of carbon (with a positive charge) (C+) has 6 protons but only 5 electrons.So yes, in a standard atom, the number of protons=the number of electrons
What does neutral atom have equal number of?
a neutrally charged atom has an equal number of both protons and neutrons, making the positive and negative charges the same. for example, in a neutrally charged atom, there would be 1 neutron and 1 proton.
What element is composed of atoms with the same number of neutrons or protons?
Ideally, all elements should have the same number of protons, neutrons and electrons unless they become ionic. This is how elements such as the noble gases remain stable. They the same number of electrons, protons, and neutrons, and a full octet.
Is an atom of nitrogen with 7 protons 8 neutrons and 8 electrons an ion?
Yes. An uncharged atom has the same number of protons (+ve charge) and electrons (-ve charge). An atom with 7 protons and 8 electrons has an overall charge of [+7+(-8)=-1] so is an ion, it is called an 'anion' because it is negative. Positive ions are 'cations'.
What will an alpha particle change into when it absorbs two electrons?
When an alpha particle absorbs two electrons, it will become a helium atom. This is because an alpha particle is essentially a helium nucleus consisting of two protons and two neutrons, and by also gaining two electrons, it will form a stable helium atom with two protons, two neutrons, and two electrons.
