elements in same group have the same number of valence electrons
The isoelectronic chemical entities.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
All elements in the same group have the same number of valence electrons.
all the elements in group A has the same number of valence electrons
Families or _GROUPS_ of elements are similar due to similarities in their number of valence electrons.Answer:
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
Elements in the same group have the same number of valence electrons.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
All elements in the same group have the same number of valence electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
All elements in the same group have the same number of valence electrons.
All elements in the same A group will have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
all the elements in group A has the same number of valence electrons
what term describes elements that contain the same number of valence electrons
Elements in same column have equal number of valence electrons. so they possess similar chemical properties.
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
