What is a Semimetal in group 5A?
Group 5A. Nitrogen and phosphorus are non-metals, arsenic is a semimetal, and antimony and bismuth tend to be metallic, typically forming ions with a +3 charge.

How many groups are in the periodic table?
Groups are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.
What are the general properties of metalloids?
Metalloids tend to be shiny like metals, but brittle like nonmetals. Because they are brittle, they may chip like glass or crumble to a powder if struck. Other physical properties of metalloids are more variable, including their boiling and melting points, although all metalloids exist as solids at room temperature.
What happens to metals in group 5A 6A and 7A when they form ions?
Metals in Groups 1A, 2A and 3A will form ions with 1+, 2+ and 3+ charges, respectively. … Thus Group 5A elements can accept three electrons to form 3- ions, Group 6A elements accept two electrons to form 2- ions and Group 7A elements (the halogens) accept one electron to form 1- ions.

How many electrons are in the highest occupied energy level of an element in group 5A?
and so on. As you know, an element’s valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group 5A has 5 electrons on its highest occupied energy level.

What element is in group 18 period?
Period 1. The first period contains fewer elements than any other, with only two, hydrogen and helium. They therefore do not follow the octet rule, but rather a duplet rule. Chemically, helium behaves like a noble gas, and thus is taken to be part of the group 18 elements.
Why is there a large variation in properties among group 5A elements?
More commonly, the group 5A element acquires an octet of electrons via covalent bonding. … The variation in properties among the elements of group 5A is more striking than that seen in groups 6A and 7A.

What charge does group 4A have?
If an element loses all four valence electrons in 4A, it gets a charge of +4, also referred to as an oxidation state of +4. Generally, the elements at the top of this group have an oxidation state of +4 while the elements at the bottom have a state of +2, but when we analyse each element.
Which of the following is an oxidation state of the group 5A elements?
The most common oxidation numbers for Group 5A elements are 3, 5, and 3. Nitrogen has oxidation numbers from 3 to 5 in a variety of stable compounds. Elemental nitrogen, N2, is highly unreactive due to its strong N-to-N triple bond.
Where is fluorine on the periodic table?
fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
What is N electronegativity?
The first scale of electronegativity was developed by Linus Pauling and on his scale nitrogen has a value of 3.04 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).
What is group 8A of the periodic table called?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
