As you move across the Periodic Table the elements gain a proton and an electron at each stage. This makes the nucleus larger each step you take and also increases the number of electrons in the outer shell. The number of electrons in the outer shell affects reactivity, too few and the element is reactive because it wants to lose them to get a full outer shell, too many (but not quite full) and it is reactive because it wants to add electrons to get a full shell.
they change because the numbers of valence electrons within a group change.
it decreases
They become less reactive.
di ko po alam ehhh
The groups each have different names. Group one is made up of Alkali Metals (except for Hydrogen). Group two is made of Alkali Earth Metals. The other groups include Transition Metals, Noble Gases, Poor Metals and Non Metals.
No such thing, because when you zoom in down to the nano scale gold is not gold anymore as its properties change at the nano scale.
What are the 3 properties of metals?
No, they are not.
metals
They become less reactive.
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
Yes, elements generally change from metals to non-metals from left to right across the periodic table. In the periodic table, elements are arranged in order of increasing atomic number, and as you move across a period from left to right, the properties of the elements change from metallic to non-metallic. The left side of the periodic table consists of metals, the middle consists of metalloids, and the right side consists of non-metals.
Because they may fuse, block or displace other metals! :)
The melting temperature properties generally change as you go down the columns of the Periodic Table by decreasing for metals and increasing for non-metals.
The metalloids have properties of both metals and nonmetals.

all family of periodic table thier properties and uses
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
No such thing, because when you zoom in down to the nano scale gold is not gold anymore as its properties change at the nano scale.

No, metalloids have properties of metals and nonmetals.
