What group of atoms gives DNA its electric charge?
The charge from the protons and electrons. If an atom loses an electron, it will have a net positive charge. If an atom gains an extra electron, it will have a net negative charge.
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
3 parts of the atom?
The electron (negative charge), the neutron (neutral charge), and the proton (positive charge). The neutrons and protons are both found in the nucleus of the atom, while the electrons are on the outside circling the atom.
What is the difference in the number of protons and electrons in an atom?
The number of protons (each has charge = +1) in an atom identify the element, e.g. hydrogen (1 proton), helium (2 protons), etc. If the number of electrons is the same, then the atom is neutral (total charge = 0). For example, a lithium atom has three protons in the nucleus (charge = +3) and three electrons (charges -1,-1,-1). The total charge is +3 -1 -1 -1 = 0. If the number of electrons is different than the number of protons, as when lithium would lose an electron, we say the lithium atom has been ionized--it is now a lithium ion and the charge is +3 -1 -1 = +1. If the lithium ion loses another electron, we would say it is doubly ionized or twice ionized and the charge would be +3 -1 = +2.
What Does lithium become an anion or cation?
Lithium has 3 protons and three electrons in its neutral state. In a higher energy state, it loses its outer electron to become Li+ or ionized lithium. Lithium is in group 1 on the periodic table. This means that it has only 1 valence electron. Lithium will tend to lose that electron when it ionizes and become an ion. An ion is any atom or molecule with a charge. When Li loses the electron, it loses one of its negative charges so the atom becomes an ion with a +1 charge because it now has 3 positively charged protons and only 2 negatively charged electrons.
Does an element that loses 3 electrons have a charge of plus 2?
If an atom loses 3 electrons, it gets a charge of +3. (One positive charge for every electron lost). If an atom loses 2 electrons, it gets a charge of +2.
What is the charge of an element if it loses an electron?
It depends on the charge on the atom at the start before it gains an electron. The electron has a charge of -1, and will make an atom more negative or less positive (both of which are the same thing). Let's look at the possibilities. If an atom is neutral (zero net charge) and gains an electron, it has a net charge of -1. If an atom is at +1 and gains an electron, it has a net charge of zero. If an atom has any positive charge, p, above +1, it has a net charge of p - 1. (A +5 would become a +4, and a +3 would become a +2.) If an atom has any negative charge, n, then its net charge becomes n - 1. (A -4 would become a -5, and a -2 would become a -3.)
What is the charge on a neutral atom if it loses 3 electrons?
Depending on the atom, if it loses an electron it will become positively charged. In some cases it will also become unstable. All stable atoms are neutral, because there is always an equal amount of positively charged protons as there are negativity charged electrons. If the atom loses a positively charged proton, then the overall charge of the atom will become negative and vice versa.
What group of atoms gives DNA its electric charge?
The charge from the protons and electrons. If an atom loses an electron, it will have a net positive charge. If an atom gains an extra electron, it will have a net negative charge.
What kind of charge will an atom have if it gains or loses one or more electrons?
If an atom loses an electron, it will be positively charged. An example may make this clearer. A neutral carbon atom has 6 protons and 6 electrons. If you take away an electron, you will have 6 protons and 5 electrons, for a total charge of +6 -5 = +1.
An atom that has gained one electron has a charge of?
-1, since each electron has a charge of -1.
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
What are the 3 partcles of the atom?
Proton, neutron, and electron. A proton has a positive charge. A neutron is neutral (no charge) and an electron has a negative charge.
What type of ion forms when an atom loses-electrons?
Cation A way to remember is that you know electrons are negatively charged, and if an atom loses an electron it becomes positively charged, pos=paws cats have paws positive ions are cations. Anions sounds like anti-ions anti is negative anions are negative.
3 parts of the atom?
The electron (negative charge), the neutron (neutral charge), and the proton (positive charge). The neutrons and protons are both found in the nucleus of the atom, while the electrons are on the outside circling the atom.
How many electrons are there in the lithium ion?
Lithium loses one electron when fulfilling the octet rule. A neutral atom of lithium will have the same number of electrons as protons, 3. Therefore, a lithium ion will have one less electron, 2.
When an aluminum atom loses it's valence electrons what is the charge on the resulting ion?
Aluminum loses 3 electrons. Since electrons have a negative charge losing them would make the aluminum atom lessnegative, which is positive. Hence, Al+3
