Is this true atoms lose protons but seldom lose or gain electrons?
i really don't know so can someone answer it that knows
Why is an atom with fewer electrons in the outer shell more reactive?
That isn't really true. What makes atoms more reactive is if their electronic configuration is nearly that of a noble gas -- in other words is either has just one or two electrons less or more than a noble gas.So elements with either 1, 2, 6 or 7 valence electrons tend to be especially reactive.so the guy who gave the first answer doesnt know what hes talking about.
Circle the letter of each sentence that is true about alkaline earth metals?
a. each is a good conductor of electricity b. they are never found uncombined in nature c. they lose two electrons in chemical reactions
Is it true that electrons are arranged in different energy levels in an atom?
It simply means that electrons can only have certain energies. These "levels" are often in terms of n, such as n1, n2, n3, and so on. Let's say that n1=1000 eV (a unit for energy) and n2=2000 eV. It would be impossible for an electron in an atom to have any energy between those two values. This follows true for any energy level; this can be shown better like this: there can be no electron energy found between nx and nx+1 when the electron is in an atom.
Can clustering objects or elements in a piece of art is one way to achieve unity?
true
Do isotopes exist because atoms of the same element can have different numbers of neutrons?
Yes, it is true. Isotopes have the same number of protons an electrons; the number of neutrons is different.
Ions are charged and isotopes are not true or false?
True. Isotopes are defined by the amount of neutral neutrons which have no effect on the polarity of the atom. ions are defined by a differing amount of protons and electrons, therefore charging them.
Which is not true all isotopes of an element have the same number of electrons?
All neutral atoms of an element, including any of its isotopes, always do have the same number of electrons. The existence of isotopes has nothing to do with the number of electrons in an atom. Instead, the number of neutrons varies between isotopes of the same element. The number of electrons varies from that of a neutral atom only if an ion of the element is formed.
True or false two isotopes of carbon are carbon-12 and carbon-14 theese isotopes differ from one another by two ELECTRONS?
False. Carbon-12 and carbon-14 are isotopes of carbon that differ in the number of neutrons in their nuclei, not electrons. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. The number of electrons in an atom is determined by its atomic number, which is the same for both isotopes of carbon (6 electrons).
Which statement is true Isotopes are atoms of different elements with equal mass. For the same element they have equal numbers of neutrons. Isotopes of a given element have similar chemical properties?
For the same element, isotopes have equal numbers of protons but different numbers of neutrons. Isotopes of a given element have similar chemical properties due to having the same number of electrons, which determines an element's chemical behavior.
Is it true Different isotopes for the same element will always have the same numbers of neutrons?
Yes. it is true. Isotopes of the same element always have different number of neutrons.
Is it true or false that isotopes are forms of an element that have the same number of protons but a different number of electrons?
False. Isotopes are forms of an element that have the same number of protons but a different number of neutrons. Electrons are not involved in determining an element's identity.
Is mixtures or isotopes are atoms of the same element with different numbers of neutrons?
Isotopes are atoms of the same element with different numbers of neutrons. Mixtures, on the other hand, are combinations of different substances that are physically mixed together, but not chemically bonded.
What is the set of numbers that can be substituted for the variable and keep the sentence true?
solution set
Is it true that atoms with the same number of protons but diffrent numbers of neutrons are called isomers?
Not isomers, Isotopes
Do isotopes have a different mass because of the number of electrons?
the differences in neutrons of the elements
What does it mean for a coordinate pair to be a solution to a system of equations?
It means that if you replace one variable with one of the numbers, and the other variable with the other numbers, and then evaluate the expressions on each side of the equations, the equalities will be true.
