Group eight
main group elements
No. noble gases are group VIIIA or group 18 elements
A group of format specifications that are assigned a name is called a format setting or format template. This allows for easy re-use of the format specifications by referring to the assigned name when formatting data.
There are 4 elements in group-4.
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Basically they are classified on the basis of repetition of similar properties......... Elements with same properties are assigned according to their groups.......each member of a particular group in a periodic table resembles almost similar properties elements with electron entering same shell is assigned same period....Thats how elements are classified
Roles should be assigned so everyone has a part in the group and no one will be left out.
to the group in which participants are representative of people in general.
each atom has its own attraction for electrons called electronegativity. This electronegetivity is determined by- -number of protons -size of electron cloud (distance of valence electrons from the nucleus) - and number of valence electrons the elements with low electronegetivity are called metals, and those with high electronegetivity are non-metals. Flourine has the highest electronegetivity- 4 Francium has the lowest. in an ionic bond, one of the atoms involved must have a low electronegetivity, and the other a high electronegetivity (difference must be greater than or equal to 1.7). the atom that has a high electronegetivity is generally a non-metal, and the other is generally a metal. when the metal collides with the non-metal, the valence electron from the metal is stripped off by the non-metal. the non-metal gains the electron, leaving it with a net negative charge. The metal, having lost a negative charge, is left with a net positive charge. This difference in charges holds the two ions together, forming the ionic bond.
A group of people assigned to one task is commonly referred to as a team.
elements are in the same group since they react similarly to other elements in that group.
main group elements
There is a total of 17 elements in those groups.
No. noble gases are group VIIIA or group 18 elements
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
