What else can I help you with?
Why is any atom neutral?
The atom has the same number of electrons as protons. electrons are negatively charged, and protons are positively charged. So for example in a Helium atom, it has 2 protons and 2 electrons, so the sub-particles cancel out, making the atom neutral.
What will happen to an atom is an alpha particles emits or adds?
Alpha particles are emitted from the atom taking with it 2 protons and (I am pretty sure) two neutrons. This will change the atomic number of the atom and the atomic weight.
How many elements are in a atom?
i don't know about 2
What are the 2 things that have the same number in an atom?
The number of protons and the number of electrons.
Do alpha prarticle share the same atomic number?
An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.
What 2 subatomic particles can you determine from the atomic number?
Atomic number is same as the number of protons and number of electrons.
How many protons does an atom have if it looses 2 electrons?
The same number of protons.
How do you find out how many protons an atom has?
Every element has its own unique atomic number. The atomic number tells how many protons are in 1 atom of that element. Since no 2 elements have the same same atomic number, no 2 elements have the same number of protons. Basically, the atomic # is the same as the # of protons. For example: Aluminum= ''Al'' has an atomic # of 13, so it has 13 protons.
Which 2 particles in an atom are equal?
electrons and protons
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
As you move down group 2 in the periodic table, the number of valence electrons in each atom remains the same, at 2. This is because elements in the same group have the same number of valence electrons, regardless of the period they are in.
Where are these subatomic particles within the atom?
There are three types of subatomic particles: neutrons (neutral), protons (positive) and electrons (negative). The protons and neutrons are stuck together at the very centre of an atom with the electrons 'flying' around the outside. The atomic number of an element refers to how many protons are in an atom, for example helium (atomic number 2) has two protons in the centre.
How many electrons are on a boron atom?
5- the atomic number of boron is 5. Atomic number is the number of protons and this is the same as the number of electrons in the neutral atom.
