What are 3 things that elements in the same column have in common?
Explanation: For the elements in column 1,2 and 13-18 the atoms in the same column have the same amount of outermost electrons, called valence electrons. Atoms in column 1 (H, Li and Na for example) have 1 valence electron. Column 2 have 2 valence electrons, 13 have 3, 14 have 4 and so on.
What are the names of the 4 columns of the periodic table?
Vocabulary
- Group (family): A vertical column in the periodic table.
- Alkali metals: Group 1A of the periodic table.
- Alkaline earth metals: Group 2A of the periodic table.
- Halogens: Group 7A of the periodic table.
- Noble gases: Group 8A of the periodic table.
- Transition elements: Groups 3 to 12 of the periodic table.
What are the 10 families of elements?
Terms in this set (10)
- alkali family. group 1, hydrogen is not a member.
- alkaline earth. group 2, also very reactive, only 2 valence electrons.
- transition metals.
- boron family.
- carbon family.
- nitrogen family.
- oxygen family.
- halogen family.
Which family of the periodic table is the most unique?
The halogens are a group of elements in the periodic table. They are located to the right of the other nonmetals and to the left of the noble gases. Elements in the halogen group have seven electrons in their outer shells giving them many unique properties.
What is the largest family on the periodic table?
Transition Metals
What are the 7 major families of the periodic table?
A collection of 87 elements that includes numerous families—the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides, as well as seven elements in groups 3 through5.
What is a period in Chem?
In chemical bonding: Arrangement of the elements. The horizontal rows of the periodic table are called periods. Each period corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of a d subshell.
What are the 4 main properties of metals?
Properties of metals
- high melting points.
- good conductors of electricity.
- good conductors of heat.
- high density.
- malleable.
- ductile.
What elements have the same properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
What element is most similar to oxygen?
Explanation: Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties. Sulfur and selenium are the next two elements in the group, and they react with hydrogen gas (H2) in a manner similar to oxygen.
What element has properties like calcium?
Metal
Which type of elements are likely to have no?
Answer: Atoms of all elements – except for most atoms of hydrogen – have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge – they are electrically neutral.
What is two or more elements combined?
When two or more elements combine to form a new substance, it is called a compound. There are many different types of compounds, because atoms of elements combine in many different ways to form different compounds.
What is the difference of elements and compounds?
Element: Pure substance consisting of one type of atom. Compound: Pure substance consisting of two or more different atoms. Mixture: Two or more different substances not chemically combined.
Which elements are likely to gain electrons?
nonmetals
Which group gains electrons most easily?
Nonmetals
How do you know which elements gain or lose electrons?
Explanation: In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. Hydrogen is an exception, as it will usually lose its electron. Metalloids and some metals can be can lose or gain electrons.
What elements gain 2 electrons?
For example, oxygen atoms gain two electrons to form O2- ions. These have the same electron configuration as the noble gas neon. Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure.
Which group has elements that have a 2 charge?
alkali earth metals
What forms after an atom loses electrons?
An atom loses electrons to form a cation , that is a positively charged ion (and one that is attracted towards the negatively charged terminal, the cathode ).
Do elements in Group 4 gain or lose electrons?
All elements in this group tend to lose their valence electrons. If an element in 4A loses all four valence electrons it gets a +4 charge, also known as a +4 oxidation state. Finally, most form covalent bonds, or when electrons are shared between atoms.
Are the elements in Group 4 very reactive?
All the group 4 elements are hard, refractory metals. Their inherent reactivity is completely masked due to the formation of a dense oxide layer that protects them from corrosion, as well as attack by many acids and alkalis.
How many electrons does group 4 have?
The Group 4 atoms have 4 valence electrons. The Group 5 atoms have 5 valence electrons.
Does Group 5 gain or lose electrons?
Groups 5,6,7 contain non-metals and they gain electrons (e-) to make stable ions.
Does Group 6A gain or lose electrons?
Atoms in Group 6A have 6 valence electrons and gain 2 more electrons to get octet. These anions have -2 charge. Atoms in Group 7A have 7 valence electrons and gain 1 more electron to get octet.
How many electrons do group 5 elements have in their outer shell?
The ‘V’ is the Roman numeral for five and represents the number of electrons in the outer orbital. All of that information tells you there are two electrons in the first orbital and five in the second (2-5). Phosphorus (P) is also in Group VA which means it also has five electrons in its outer orbital.
What is the relationship between the group number and the number of outer electrons?
the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in. the number of electrons in all shells of an element is represented in the periodic table as the element’s atomic number.
How many electrons are in the outer shell of every element in Group 1?
one electron
